Linguistic rights
The constitution of India was first drafted on January 26, 1950. It is estimated that there are about 1500 languages in India. Article 343–345 declared that the official languages of India for communication with centre will be Hindi and English. There are 22 official languages identified by constitution. Article 345 states that "the Legislature of a state may by law adopt any one or more of the languages in use in the State or Hindi as the language or languages to be used for all or any of the official purposes of that State: Provided that, until the Legislature of the State otherwise provides by law, the English language shall continue to be used for those official purposes within the State for which it was being used immediately before the commencement of this Constitution".
Bharati Braille
Bharati braille ( ), or Bharatiya Braille (Hindi: "" "Indian braille"), is a largely unified braille script for writing the languages of India. When India gained independence, eleven braille scripts were in use, in different parts of the country and for different languages. By 1951 a single national standard had been settled on, Bharati braille, which has since been adopted by Sri Lanka, Nepal, and Bangladesh. There are slight differences in the orthographies for Nepali in India and Nepal, and for Tamil in India and Sri Lanka. There are significant differences in Bengali Braille between India and Bangladesh, with several letters differing. Pakistan has not adopted Bharati braille, so the Urdu Braille of Pakistan is an entirely different alphabet than the Urdu Braille of India, with their commonalities largely due to their common inheritance from English or International Braille. Sinhalese Braille largely conforms to other Bharati, but differs significantly toward the end of the alphabet, and is covered in its own article.
