U+1F2F "Ἧ" Greek Capital Letter Eta with Dasia and Perispomeni Unicode Character
Unicode Version 17.0
Ἧ
U+1F2F "Ἧ" Greek Capital Letter Eta with Dasia and Perispomeni is a historical Greek letter used in polytonic orthography to represent an eta (Η) that begins with a rough breathing mark (dasia, indicating an initial /h/ sound) and a circumflex accent (perispomeni, indicating a rising and falling pitch). This character appears in ancient and liturgical Greek texts, often in words where the long eta vowel carries a specific tonal and aspirated pronunciation, such as in certain forms of the Greek definite article or conjunctions. As part of the Greek Extended block, it preserves the nuanced phonetic and accentual details of classical and medieval Greek writing, though it is no longer used in modern monotonic Greek.
