Unicode is a computing industry standard for the consistent encoding and handling of text expressed in most of the worlds writing systems. As of June 2016, the most recent version is Unicode 9.0, the standard is maintained by the Unicode Consortium. Unicodes success at unifying character sets has led to its widespread, the standard has been implemented in many recent technologies, including modern operating systems, XML, and the. NET Framework. Unicode can be implemented by different character encodings, the most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit for each character but cannot encode every character in the current Unicode standard, UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units to handle each of the additional characters.
Many traditional character encodings share a common problem in that they allow bilingual computer processing, Unicode, in intent, encodes the underlying characters—graphemes and grapheme-like units—rather than the variant glyphs for such characters. In the case of Chinese characters, this leads to controversies over distinguishing the underlying character from its variant glyphs. In text processing, Unicode takes the role of providing a unique code point—a number, in other words, Unicode represents a character in an abstract way and leaves the visual rendering to other software, such as a web browser or word processor. This simple aim becomes complicated, because of concessions made by Unicodes designers in the hope of encouraging a more rapid adoption of Unicode, the first 256 code points were made identical to the content of ISO-8859-1 so as to make it trivial to convert existing western text. For other examples, see duplicate characters in Unicode and he explained that he name Unicode is intended to suggest a unique, universal encoding.
In this document, entitled Unicode 88, Becker outlined a 16-bit character model, Unicode could be roughly described as wide-body ASCII that has been stretched to 16 bits to encompass the characters of all the worlds living languages. In a properly engineered design,16 bits per character are more than sufficient for this purpose, Unicode aims in the first instance at the characters published in modern text, whose number is undoubtedly far below 214 =16,384. By the end of 1990, most of the work on mapping existing character encoding standards had been completed, the Unicode Consortium was incorporated in California on January 3,1991, and in October 1991, the first volume of the Unicode standard was published. The second volume, covering Han ideographs, was published in June 1992, in 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. The Microsoft TrueType specification version 1.0 from 1992 used the name Apple Unicode instead of Unicode for the Platform ID in the naming table, Unicode defines a codespace of 1,114,112 code points in the range 0hex to 10FFFFhex.
Normally a Unicode code point is referred to by writing U+ followed by its hexadecimal number, for code points in the Basic Multilingual Plane, four digits are used, for code points outside the BMP, five or six digits are used, as required. Code points in Planes 1 through 16 are accessed as surrogate pairs in UTF-16, within each plane, characters are allocated within named blocks of related characters
Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth. Alveolar consonants may be articulated with the tip of the tongue, as in English, or with the flat of the tongue just above the tip, as in French and Spanish. The laminal alveolar articulation is often called dental, because the tip of the tongue can be seen near to or touching the teeth. The International Phonetic Alphabet does not have symbols for the alveolar consonants. Rather, the symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar sh. To disambiguate, the bridge may be used for a dental consonant, note that differs from dental in that the former is a sibilant and the latter is not. Differs from postalveolar in being unpalatalized, the bare letters, etc. cannot be assumed to specifically represent alveolars. If it is necessary to specify a consonant as alveolar, a diacritic from the Extended IPA may be used, the letters ⟨s, t, n, l⟩ are frequently called alveolar, and the language examples below are all alveolar sounds.
Alveolar consonants are transcribed in the IPA as follows, The alveolar or dental consonants and are, along with, there are a few languages that lack them. A few languages on Bougainville Island and around Puget Sound, such as Makah, lack nasals and therefore, colloquial Samoan, lacks both and, but it has a lateral alveolar approximant /l/. In Standard Hawaiian, is an allophone of /k/, but /l/, in labioalveolars, the lower lip contacts the alveolar ridge. Such sounds are typically the result of a severe overbite, the Sounds of the Worlds Languages
Queensland is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west, to the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,750,500, concentrated along the coast, the state is the worlds sixth largest sub-national entity, with an area of 1,852,642 km2. The capital and largest city in the state is Brisbane, Australias third largest city, often referred to as the Sunshine State, Queensland is home to 10 of Australias 30 largest cities and is the nations third largest economy. Tourism in the state, fuelled largely by its tropical climate, is a major industry. Queensland was first inhabited by Aboriginal Australians and Torres Strait Islanders, the first European to land in Queensland was Dutch navigator Willem Janszoon in 1606, who explored the west coast of the Cape York Peninsula near present-day Weipa.
In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain. The colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney, New South Wales at that time included all of what is now Queensland, Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement was allowed from 1842, the state was named in honour of Queen Victoria, who on 6 June 1859 signed Letters Patent separating the colony from New South Wales. The 6th of June is now celebrated statewide as Queensland Day. Queensland achieved statehood with the Federation of Australia on 1 January 1901, the history of Queensland spans thousands of years, encompassing both a lengthy indigenous presence, as well as the eventful times of post-European settlement. The north-eastern Australian region was explored by Dutch and French navigators before being encountered by Lieutenant James Cook in 1770, the Australian Labor Party has its origin as a formal organisation in Queensland and the town of Barcaldine is the symbolic birthplace of the party.
June 2009 marked the 150th anniversary of its creation as a colony from New South Wales. The Aboriginal occupation of Queensland is thought to predate 50,000 BC, likely via boat or land bridge across Torres Strait, during the last ice age Queenslands landscape became more arid and largely desolate, making food and other supplies scarce. This led to the worlds first seed-grinding technology, warming again made the land hospitable, which brought high rainfall along the eastern coast, stimulating the growth of the states tropical rainforests. In February 1606, Dutch navigator Willem Janszoon landed near the site of what is now Weipa and this was the first recorded landing of a European in Australia, and it marked the first reported contact between European and Aboriginal Australian people. The region was explored by French and Spanish explorers prior to the arrival of Lieutenant James Cook in 1770. Cook claimed the east coast under instruction from King George III of the United Kingdom on 22 August 1770 at Possession Island, naming Eastern Australia, including Queensland, the Aboriginal population declined significantly after a smallpox epidemic during the late 18th century
Specials (Unicode block)
Specials is a short Unicode block allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 codepoints, five are assigned as of Unicode 9, U+FFFD � REPLACEMENT CHARACTER used to replace an unknown, unrecognized or unrepresentable character U+FFFE <noncharacter-FFFE> not a character. FFFE and FFFF are not unassigned in the sense. They can be used to guess a texts encoding scheme, since any text containing these is by not a correctly encoded Unicode text. The replacement character � is a found in the Unicode standard at codepoint U+FFFD in the Specials table. It is used to indicate problems when a system is unable to render a stream of data to a correct symbol and it is usually seen when the data is invalid and does not match any character, Consider a text file containing the German word für in the ISO-8859-1 encoding. This file is now opened with an editor that assumes the input is UTF-8. The first and last byte are valid UTF-8 encodings of ASCII, therefore, a text editor could replace this byte with the replacement character symbol to produce a valid string of Unicode code points.
The whole string now displays like this, f�r, a poorly implemented text editor might save the replacement in UTF-8 form, the text file data will look like this, 0x66 0xEF 0xBF 0xBD 0x72, which will be displayed in ISO-8859-1 as fï¿½r. Since the replacement is the same for all errors this makes it impossible to recover the original character, a better design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence and it has become increasingly common for software to interpret invalid UTF-8 by guessing the bytes are in another byte-based encoding such as ISO-8859-1. This allows correct display of both valid and invalid UTF-8 pasted together, Unicode control characters UTF-8 Mojibake Unicodes Specials table Decodeunicodes entry for the replacement character
It is a lexicographical product which shows inter-relationships among the data. A broad distinction is made between general and specialized dictionaries, Specialized dictionaries include words in specialist fields, rather than a complete range of words in the language. Lexical items that describe concepts in specific fields are called terms instead of words. In practice, the two approaches are used for both types, there are other types of dictionaries that do not fit neatly into the above distinction, for instance bilingual dictionaries, dictionaries of synonyms, and rhyming dictionaries. The word dictionary is usually understood to refer to a general purpose monolingual dictionary, there is a contrast between prescriptive or descriptive dictionaries, the former reflect what is seen as correct use of the language while the latter reflect recorded actual use. Stylistic indications in many modern dictionaries are considered by some to be less than objectively descriptive, the birth of the new discipline was not without controversy, the practical dictionary-makers being sometimes accused by others of astonishing lack of method and critical-self reflection.
The oldest known dictionaries were Akkadian Empire cuneiform tablets with bilingual Sumerian–Akkadian wordlists, discovered in Ebla, the early 2nd millennium BCE Urra=hubullu glossary is the canonical Babylonian version of such bilingual Sumerian wordlists. Philitas of Cos wrote a pioneering vocabulary Disorderly Words which explained the meanings of rare Homeric and other words, words from local dialects. Apollonius the Sophist wrote the oldest surviving Homeric lexicon, the first Sanskrit dictionary, the Amarakośa, was written by Amara Sinha c. 4th century CE. Written in verse, it listed around 10,000 words, according to the Nihon Shoki, the first Japanese dictionary was the long-lost 682 CE Niina glossary of Chinese characters. The oldest existing Japanese dictionary, the c.835 CE Tenrei Banshō Meigi, was a glossary of written Chinese, a 9th-century CE Irish dictionary, Sanas Cormaic, contained etymologies and explanations of over 1,400 Irish words. In India around 1320, Amir Khusro compiled the Khaliq-e-bari which mainly dealt with Hindavi, in medieval Europe, glossaries with equivalents for Latin words in vernacular or simpler Latin were in use.
The Catholicon by Johannes Balbus, a large grammatical work with a lexicon, was widely adopted. It served as the basis for several bilingual dictionaries and was one of the earliest books to be printed, in 1502 Ambrogio Calepinos Dictionarium was published, originally a monolingual Latin dictionary, which over the course of the 16th century was enlarged to become a multilingual glossary. The first monolingual dictionary written in Europe was the Spanish, written by Sebastián Covarrubias Tesoro de la lengua castellana o española, published in 1611 in Madrid, in 1612 the first edition of the Vocabolario dellAccademia della Crusca, for Italian, was published. It served as the model for works in French and English. In 1690 in Rotterdam was published, the Dictionnaire Universel by Antoine Furetière for French, in 1694 appeared the first edition of the Dictionnaire de lAcadémie française. Between 1712 and 1721 was published the Vocabulario portughez e latino written by Raphael Bluteau, the Totius Latinitatis lexicon by Egidio Forcellini was firstly published in 1777, it has formed the basis of all similar works that have since been published
A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology, other terms occasionally encountered are domal and cacuminal. The Latin-derived word retroflex means bent back, some consonants are pronounced with the tongue fully curled back so that articulation involves the underside of the tongue tip. These sounds are described as true retroflex consonants. Retroflex consonants, like other consonants, come in several varieties. The tongue may be flat or concave, or even with the tip curled back. The point of contact on the tongue may be with the tip, with the blade, the point of contact on the roof of the mouth may be with the alveolar ridge, the area behind the alveolar ridge, or the hard palate. Finally, both sibilant and nonsibilant consonants can have a retroflex articulation, the greatest variety of combinations occurs with sibilants, because for these, small changes in tongue shape and position cause significant changes in the resulting sound.
Retroflex sounds in general have a duller, lower-pitched sound than other alveolar or postalveolar consonants, and especially the grooved alveolar sibilants. The farther back the point of contact with the roof of the mouth, the concave is the shape of the tongue. The main combinations normally observed are, Laminal post-alveolar, with a flat tongue and these occur, for example, in Polish cz, sz, ż, dż and Mandarin zh, ch, sh, r. Apical post-alveolar, with a somewhat concave tongue and these occur, for example, in Hindi and other Indo-Aryan languages. Subapical palatal, with a highly concave tongue and these occur particularly in the Dravidian languages. These are the dullest and lowest-pitched type, and when following a vowel often add strong r-coloring to the vowel and these are not a place of articulation, as the IPA chart implies, but a shape of the tongue analogous to laminal and apical. Apical alveolar, with a somewhat concave tongue and these occur, for example, in peninsular Spanish and Basque.
These sounds dont quite fit on the front-to-back, laminal-to-subapical continuum, with a relatively dull, the subapical sounds are sometimes called true retroflex because of the curled-back shape of the tongue, while the other sounds sometimes go by other names. For example and Maddieson prefer to call the laminal post-alveolar sounds flat post-alveolar, the retroflex approximant /ɻ/ is an allophone of the alveolar approximant /ɹ/ in many dialects of American English, particularly in the Midwestern United States. Polish and Russian possess retroflex sibilants, but no stops or liquids at this place of articulation, in African languages retroflex consonants are very rare, reportedly occurring in a few Nilo-Saharan languages
International Phonetic Alphabet
The International Phonetic Alphabet is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a representation of the sounds of spoken language. The IPA is used by lexicographers, foreign students and teachers, speech-language pathologists, actors, constructed language creators. The IPA is designed to represent only those qualities of speech that are part of language, phonemes, intonation. IPA symbols are composed of one or more elements of two types and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a letter, or with a letter plus diacritics. Often, slashes are used to signal broad or phonemic transcription, thus, /t/ is less specific than, occasionally letters or diacritics are added, removed, or modified by the International Phonetic Association. As of the most recent change in 2005, there are 107 letters,52 diacritics and these are shown in the current IPA chart, posted below in this article and at the website of the IPA.
In 1886, a group of French and British language teachers, led by the French linguist Paul Passy, for example, the sound was originally represented with the letter ⟨c⟩ in English, but with the digraph ⟨ch⟩ in French. However, in 1888, the alphabet was revised so as to be uniform across languages, the idea of making the IPA was first suggested by Otto Jespersen in a letter to Paul Passy. It was developed by Alexander John Ellis, Henry Sweet, Daniel Jones, since its creation, the IPA has undergone a number of revisions. After major revisions and expansions in 1900 and 1932, the IPA remained unchanged until the International Phonetic Association Kiel Convention in 1989, a minor revision took place in 1993 with the addition of four letters for mid central vowels and the removal of letters for voiceless implosives. The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap, apart from the addition and removal of symbols, changes to the IPA have consisted largely in renaming symbols and categories and in modifying typefaces.
Extensions to the International Phonetic Alphabet for speech pathology were created in 1990, the general principle of the IPA is to provide one letter for each distinctive sound, although this practice is not followed if the sound itself is complex. There are no letters that have context-dependent sound values, as do hard, the IPA does not usually have separate letters for two sounds if no known language makes a distinction between them, a property known as selectiveness. These are organized into a chart, the chart displayed here is the chart as posted at the website of the IPA. The letters chosen for the IPA are meant to harmonize with the Latin alphabet, for this reason, most letters are either Latin or Greek, or modifications thereof. Some letters are neither, for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a question mark
Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the worlds sixth-largest country by total area, the neighbouring countries are Papua New Guinea and East Timor to the north, the Solomon Islands and Vanuatu to the north-east, and New Zealand to the south-east. Australias capital is Canberra, and its largest urban area is Sydney, for about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages classifiable into roughly 250 groups. The population grew steadily in subsequent decades, and by the 1850s most of the continent had been explored, on 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Australia has since maintained a liberal democratic political system that functions as a federal parliamentary constitutional monarchy comprising six states.
The population of 24 million is highly urbanised and heavily concentrated on the eastern seaboard, Australia has the worlds 13th-largest economy and ninth-highest per capita income. With the second-highest human development index globally, the country highly in quality of life, education, economic freedom. The name Australia is derived from the Latin Terra Australis a name used for putative lands in the southern hemisphere since ancient times, the Dutch adjectival form Australische was used in a Dutch book in Batavia in 1638, to refer to the newly discovered lands to the south. On 12 December 1817, Macquarie recommended to the Colonial Office that it be formally adopted, in 1824, the Admiralty agreed that the continent should be known officially as Australia. The first official published use of the term Australia came with the 1830 publication of The Australia Directory and these first inhabitants may have been ancestors of modern Indigenous Australians. The Torres Strait Islanders, ethnically Melanesian, were originally horticulturists, the northern coasts and waters of Australia were visited sporadically by fishermen from Maritime Southeast Asia.
The first recorded European sighting of the Australian mainland, and the first recorded European landfall on the Australian continent, are attributed to the Dutch. The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken captained by Dutch navigator, Willem Janszoon. He sighted the coast of Cape York Peninsula in early 1606, the Dutch charted the whole of the western and northern coastlines and named the island continent New Holland during the 17th century, but made no attempt at settlement. William Dampier, an English explorer and privateer, landed on the north-west coast of New Holland in 1688, in 1770, James Cook sailed along and mapped the east coast, which he named New South Wales and claimed for Great Britain. The first settlement led to the foundation of Sydney, and the exploration, a British settlement was established in Van Diemens Land, now known as Tasmania, in 1803, and it became a separate colony in 1825. The United Kingdom formally claimed the part of Western Australia in 1828.
Separate colonies were carved from parts of New South Wales, South Australia in 1836, Victoria in 1851, the Northern Territory was founded in 1911 when it was excised from South Australia
In phonetics, a vowel is a sound in spoken language, with two competing definitions. There is no build-up of air pressure at any point above the glottis and this contrasts with consonants, such as the English sh, which have a constriction or closure at some point along the vocal tract. In the other, phonological definition, a vowel is defined as syllabic, a phonetically equivalent but non-syllabic sound is a semivowel. In oral languages, phonetic vowels normally form the peak of many to all syllables, whereas consonants form the onset and coda. Some languages allow other sounds to form the nucleus of a syllable, the word vowel comes from the Latin word vocalis, meaning vocal. In English, the vowel is commonly used to mean both vowel sounds and the written symbols that represent them. The phonetic definition of vowel does not always match the phonological definition, the approximants and illustrate this, both are produced without much of a constriction in the vocal tract, but they occur at the onset of syllables. A similar debate arises over whether a word like bird in a dialect has an r-colored vowel /ɝ/ or a syllabic consonant /ɹ̩/.
The American linguist Kenneth Pike suggested the terms vocoid for a vowel and vowel for a phonological vowel, so using this terminology. Nonetheless, the phonetic and phonemic definitions would still conflict for the syllabic el in table, or the syllabic nasals in button, daniel Jones developed the cardinal vowel system to describe vowels in terms of the features of tongue height, tongue backness and roundedness. These three parameters are indicated in the schematic quadrilateral IPA vowel diagram on the right, there are additional features of vowel quality, such as the velum position, type of vocal fold vibration, and tongue root position. This conception of vowel articulation has been known to be inaccurate since 1928, Peter Ladefoged has said that early phoneticians. Thought they were describing the highest point of the tongue, and they were actually describing formant frequencies. The IPA Handbook concedes that the quadrilateral must be regarded as an abstraction. Vowel height is named for the position of the tongue relative to either the roof of the mouth or the aperture of the jaw.
However, it refers to the first formant, abbreviated F1. Height is defined by the inverse of the F1 value, The higher the frequency of the first formant, however, if more precision is required, true-mid vowels may be written with a lowering diacritic. Although English contrasts six heights in its vowels, they are interdependent with differences in backness and it appears that some varieties of German have five contrasting vowel heights independently of length or other parameters
Vowel harmony is a type of long-distance assimilatory phonological process involving vowels that occurs in some languages. A vowel or vowels in a word must be members of the same subclass, in languages with vowel harmony, there are constraints on which vowels may be found near each other. Suffixes and prefixes will usually follow vowel harmony rules, many agglutinative languages have vowel harmony. The term vowel harmony is used in two different senses, in the first sense, it refers to any type of long distance assimilatory process of vowels, either progressive or regressive. When used in this sense, the vowel harmony is synonymous with the term metaphony. In the second sense, vowel harmony refers only to progressive vowel harmony, for regressive harmony, the term umlaut is used. In this sense, metaphony is the term while vowel harmony. The term umlaut is used in a different sense to refer to a type of vowel gradation. This article will use vowel harmony for both progressive and regressive harmony, harmony processes are long-distance in the sense that the assimilation involves sounds that are separated by intervening segments.
In other words, harmony refers to the assimilation of sounds that are not adjacent to each other, for example, a vowel at the beginning of a word can trigger assimilation in a vowel at the end of a word. The assimilation occurs across the word in many languages. This is represented schematically in the diagram, In the diagram above. The vowel that causes the vowel assimilation is frequently termed the trigger while the vowels that assimilate are termed targets, when the vowel triggers lie within the root or stem of a word and the affixes contain the targets, this is called stem-controlled vowel harmony. This is fairly common among languages with vowel harmony and may be seen in the Hungarian dative suffix, the -nak form appears after the root with back vowels. The -nek form appears after the root with front vowels, some languages have more than one system of harmony. For instance, Altaic languages are proposed to have a rounding harmony superimposed over a backness harmony, even among languages with vowel harmony, not all vowels need participate in the vowel conversions, these vowels are termed neutral.
Neutral vowels may be opaque and block harmonic processes or they may be transparent, intervening consonants are often transparent. Finally, languages that do have vowel harmony often allow for lexical disharmony, for example, Turkish vakit, *vakıt would have been expected
