The Wikipedia has the following information about this codepoint:
The Gujarati script (ગુજરાતી લિપિ, transliterated: Gujǎrātī Lipi) is an abugida for the Gujarati language, Kutchi language, and various other languages. It is one of the official scripts of the Indian Republic. It is a variant of the Devanagari script differentiated by the loss of the characteristic horizontal line running above the letters and by a number of modifications to some characters.
Gujarati numerical digits are also different from their Devanagari counterparts.
