U+10AD9 "𐫙" Manichaean Letter Ayin Unicode Character

U+10AD9 "𐫙" Manichaean Letter Ayin is a glyph from the Manichaean script, an alphabet historically used for writing the Manichaean religious texts in several Middle Iranian languages, such as Middle Persian, Parthian, and Sogdian. This specific letter represents the sound "ʿ" (a voiced pharyngeal fricative) and corresponds to the Aramaic letter Ayin, from which it was originally derived as part of the broader adaptation of the Estrangela script for Manichaean liturgical and literary purposes. It belongs to the Manichaean block of the Unicode Standard, which was added to support the digital encoding of these ancient texts for scholarly research and preservation.
