U+1FA5 "ᾥ" Greek Small Letter Omega with Dasia and Oxia and Ypogegrammeni Unicode Character

U+1FA5 "ᾥ" Greek Small Letter Omega with Dasia and Oxia and Ypogegrammeni is a polytonic Greek letter used in ancient and liturgical texts to represent the long omega sound with a rough breathing mark (dasia), an acute accent (oxia), and an iota subscript (ypogegrammeni) indicating a long diphthong. This combination typically occurs in words where the omega is the final vowel of a verb or noun form and is followed by a long iota sound, often in subjunctive or optative moods, and its precise rendering requires specialized fonts and Unicode support to ensure the diacritics are correctly stacked above and below the base letter.
