Khudabadi is a script generally used by some Sindhis in India to write the Sindhi language. It is known as Vaniki and Hatkai script, Khudabadi is one of the three scripts used for writing the Sindhi language, the other being Perso-Arabic and Devanagari script. It was used by traders and merchants to record their information and rose to importance as the script began to be used to record information kept secret from other groups, the nukta has been borrowed from Devanagari for representing additional signs found in Arabic but not found in Sindhi. It is written left to right, like Sanskrit. It follows a pattern and style of other Landa scripts. The Khudabadi script has roots in the Brahmi script, like most north Indian and it appears different from other Indic scripts such as Bengali, Gurmukhi or Devanagari, but a closer examination reveals they are similar except for angles and structure. Khudabadi is an abugida in which all consonants have an inherent vowel, matras are used to change the inherent vowel.
Vowels that appear at the beginning of a word are written as independent letters, when certain consonants occur together, special conjunct symbols are used which combine the essential parts of each letter. The Khudabadi script was created by the Sindhi diaspora residing in Khudabad to send messages to their relatives. Due to its simplicity, the use of this script spread very quickly and got acceptance in other Sindhi groups for sending written letters and it continued to be in use for very long period of time. Because it was originated from Khudabad, it was called Khudabadi script, the Sindhi traders started maintaining their accounts and other business books in this new script. Schools started teaching the Sindhi language in Khudabadi script, Sindhi language is now generally written in the Arabic script, but it belongs to the Indo-Aryan language family and over seventy percent of Sindhi words are of Sanskrit origin. The historian Al-Biruni found Sindhi written in three scripts – Ardhanagari and Khudabadi, all of them variations of Devanagari, after Mir Nasir Khan Talpurs defeat, British rule commenced in Sindh.
The British called it Hindu Sindhi to differentiate it from Sindhi written in the Perso-Arabic script, a debate began, with Captain Richard Francis Burton favoring the Arabic script and Captain Stack favouring Devanagari. The Education Department should give the instructions to the schools in the script of Sindhi which can meet the circumstance and prejudices of the Mohammadan, in the year 1868, the Bombay Presidency assigned Narayan Jagannath Vaidya to replace the Abjad script used for Sindhi with the Khudabadi script. The script was decreed a standard script modified with ten vowels by the Bombay Presidency, the Khudabadi script of Sindhi language did not make further progress. Traders continued to maintain their records in this script till the independence of Pakistan in 1947, the present script predominantly used in Sindh as well as in many states in India and else, where migrants Hindu Sindhi have settled, is Arabic in Naskh styles having 52 letters. However, in circles in India and Devanagari is used for writing Sindhi
