U+1FA8 "ᾨ" Greek Capital Letter Omega with Psili and Prosgegrammeni Unicode Character
U+1FA8 "ᾨ" Greek Capital Letter Omega with Psili and Prosgegrammeni is a polytonic Greek letter that combines the capital omega (Ω) with two diacritical marks: the psili, a smooth breathing mark resembling a small comma placed above the letter to indicate the absence of an initial 'h' sound, and the prosgegrammeni, a small iota subscript written to the right of the omega that historically represented a long vowel sound or a diphthong. This character is used in ancient and liturgical Greek texts to transcribe specific phonological distinctions, particularly in words where the omega occurs with a smooth breathing and an implied iota, such as in certain forms of the dative case or in religious manuscripts. It is part of the Greek Extended Unicode block, which preserves these archaic orthographic conventions for scholarly and ecclesiastical purposes.
