U+1F25 "ἥ" Greek Small Letter Eta with Dasia and Oxia Unicode Character

U+1F25 "ἥ" Greek Small Letter Eta with Dasia and Oxia is a historical Greek letter used in ancient polytonic orthography. It represents the eta vowel (η) combined with two diacritical marks: the dasia, or rough breathing, which indicates an initial 'h' sound, and the oxia, an acute accent that marks a high pitch or stress on the syllable. This character appears in classical texts and editions of ancient Greek literature, where it helps convey precise pronunciation and prosody that were essential to the language's phonetic system but are no longer used in modern Greek writing.
