U+A647 "ꙇ" Cyrillic Small Letter Iota Unicode Character

Unicode Version 17.0

U+A647 "ꙇ" Cyrillic Small Letter Iota is a historically significant glyph from the Early Cyrillic alphabet, representing the sound of the Greek letter iota which was used primarily in transcriptions of Greek loanwords and religious texts. This letter belongs to the Cyrillic Extended-B block, which encompasses characters added to support the full range of Old Church Slavonic orthography and paleographic variants. Unlike the standard Cyrillic letter I, the iota has a distinct, often more angular or hook-like form, and it fell out of common use as the Slavic languages simplified their writing systems, making it now a rare character encountered mainly in scholarly editions of medieval manuscripts or digital typography projects that aim to preserve historical scripts.
