U+A699 "ꚙ" Cyrillic Small Letter Double O Unicode Character

U+A699 "ꚙ" Cyrillic Small Letter Double O is a glyph used in certain historical Cyrillic alphabets, specifically representing a digraph or ligature of two "O" letters. This character was employed primarily in early printed texts and manuscripts for the Old Church Slavonic or other early Slavic languages, where it functioned to denote a specific sound or orthographic convention distinct from a single "O". It belongs to the Cyrillic Extended-B block, which was added to the Unicode standard to support minority languages and historical orthographies, though the letter itself is archaic and not used in any modern, living language.
