The Kawi or Old Javanese script is a Brahmic script found primarily in Java and used across much of Maritime Southeast Asia between the 8th century and the 16th century. The script is an abugida, meaning that characters are read with an inherent vowel. Diacritics are used, either to suppress the vowel and represent a pure consonant, or to represent other vowels.

The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
