U+1F9A "ᾚ" Greek Capital Letter Eta with Psili and Varia and Prosgegrammeni Unicode Character

U+1F9A "ᾚ" Greek Capital Letter Eta with Psili and Varia and Prosgegrammeni is a complex precomposed character used in the polytonic orthography of ancient Greek, combining the capital eta (Η) with three diacritical marks: a psili (smooth breathing) indicating the absence of an initial /h/ sound, a varia (grave accent) denoting a specific high-to-low pitch contour, and a prosgegrammeni (an iota subscript written alongside the capital letter) that represents a long ē sound followed by a lost iota in certain dative or subjunctive forms. This character is primarily encountered in scholarly editions of classical texts, such as Homeric epics or Attic dramas, where it helps convey precise pronunciation and grammatical inflections that have been preserved through centuries of textual transmission.
