U+2129 "℩" Turned Greek Small Letter Iota Unicode Character
Unicode Version 17.0
℩
U+2129 "℩" Turned Greek Small Letter Iota is a typographic symbol that resembles a lowercase Greek iota rotated 180 degrees, historically used in linguistic notation to represent a voiced palatal or glottal sound, and it occasionally appears in scholarly texts or phonetic alphabets to denote a specific phonetic value distinct from the standard iota. Its inclusion in the Unicode standard allows for consistent digital representation across systems, though it remains a rare character primarily encountered in specialized academic or historical contexts rather than in everyday writing.
