U+1F27 "ἧ" Greek Small Letter Eta with Dasia and Perispomeni Unicode Character

U+1F27 "ἧ" Greek Small Letter Eta with Dasia and Perispomeni is a historical Greek letter used in polytonic orthography to represent the long vowel eta (η) with two diacritical marks. The dasia, or rough breathing mark, indicates an initial "h" sound, while the perispomeni, a circumflex accent, denotes a rising and falling pitch contour on a long vowel. This character is thus employed in ancient and liturgical Greek texts to specify both the aspiration and the specific tonal pattern of the syllable, making it essential for accurate pronunciation and scholarly transcription of classical words.
