U+1F74 "ὴ" Greek Small Letter Eta with Varia Unicode Character

U+1F74 "ὴ" Greek Small Letter Eta with Varia is a precomposed Greek letter used in polytonic orthography to represent the vowel eta (η) with a grave accent, known as varia. This diacritical mark indicates a low or falling pitch in ancient Greek pronunciation, though in modern Greek it marks stress on a syllable now bearing a rising tone. The character is part of the Greek Extended block in Unicode, which was added to support historical and liturgical texts, and it is distinct from composing eta with a combining grave accent due to its existence as a single codepoint.
