U+0345 "ͅ" Combining Greek Ypogegrammeni Unicode Character
Unicode Version 17.0
ͅ
U+0345 "ͅ" Combining Greek Ypogegrammeni is a small, subscript-like diacritical mark used in ancient and liturgical Greek writing to represent the iota subscript, an iota that originally followed a long vowel but is no longer pronounced as a separate letter. It is always combined with another character, typically a vowel letter such as alpha, eta, or omega, to form a single typographic unit in polytonic Greek orthography. This diacritic signals historical vowel length and grammatical context, and it is distinct from the Greek iota adscript which is written as a full letter alongside the vowel.
