U+1F9E "ᾞ" Greek Capital Letter Eta with Psili and Perispomeni and Prosgegrammeni Unicode Character
U+1F9E "ᾞ" Greek Capital Letter Eta with Psili and Perispomeni and Prosgegrammeni is a polytonic Greek letter used in ancient and liturgical texts to represent the long vowel eta (η) that simultaneously carries three diacritical marks. The "psili" indicates a smooth breathing mark, meaning the vowel is not preceded by an aspirated 'h' sound, while the "perispomeni" denotes a circumflex accent, signifying a rising and falling pitch on that long syllable. The "prosgegrammeni," written as a small iota subscript below the capital letter, shows that the vowel was historically followed by a long iota sound in diphthongs, a feature often found in dative case endings or subjunctive verb forms. This combined character is extremely rare in modern digital use but essential for accurately representing classical and medieval Greek orthography in scholarly editions and ecclesiastical writings.
