This character is a Other Letter and is mainly used in the Gujarati script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+0AAA forms with similar adjacent characters prevents a line break inside it.
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.
