U+1053F Caucasian Albanian Letter Inya

The Wikipedia has the following information about this codepoint:

The Caucasian Albanian script was an alphabetic writing system used by the Caucasian Albanians, one of the ancient Northeast Caucasian peoples whose territory comprised parts of the present-day Republic of Azerbaijan and Dagestan.

It was used to write the Caucasian Albanian language and was one of only two native scripts ever developed for speakers of an indigenous Caucasian language (i.e., a language that has no genealogical relationship to other languages outside the Caucasus), the other being the Georgian scripts. The Armenian language, the third language of the Caucasus and Armenian Highlands with its own native script, is an independent branch of the Indo-European language family.
