U+1FAB "ᾫ" Greek Capital Letter Omega with Dasia and Varia and Prosgegrammeni Unicode Character

U+1FAB "ᾫ" Greek Capital Letter Omega with Dasia and Varia and Prosgegrammeni is a polytonic Greek letter used in ancient and liturgical texts, combining three distinct diacritical marks. The dasia indicates a rough breathing sound, the varia denotes a grave accent, and the prosgegrammeni is a small iota that appears subscripted beneath the omega, representing a long vowel that was historically followed by a silent iota. This character is extremely rare in modern Greek but appears in scholarly editions of classical literature, such as in the Greek New Testament or Old Testament manuscripts, where it represents a capital omega with these specific phonetic and grammatical features.
