U+1F23 "ἣ" Greek Small Letter Eta with Dasia and Varia Unicode Character

U+1F23 "ἣ" Greek Small Letter Eta with Dasia and Varia is a historical Greek letter used primarily in polytonic orthography, which was the standard system for writing ancient Greek. It represents the letter eta (η) combined with two diacritical marks: the dasia, a rough breathing mark indicating an initial /h/ sound, and the varia, a grave accent that denotes a specific pitch pattern in ancient pronunciation, typically occurring on the final syllable of a word before a pause or another word. This character is now largely obsolete in modern Greek, which uses a simplified monotonic system, but it remains important for scholarly editions, classical texts, and liturgical writings.
