Bharati Braille
Bharati braille ( ), or Bharatiya Braille (Hindi: "" "Indian braille"), is a largely unified braille script for writing the languages of India.

Sinhalese Braille largely conforms to other Bharati, but differs significantly toward the end of the alphabet, and is covered in its own article.
