U+1F0F "Ἇ" Greek Capital Letter Alpha with Dasia and Perispomeni Unicode Character

U+1F0F "Ἇ" Greek Capital Letter Alpha with Dasia and Perispomeni is a precomposed glyph used in polytonic Greek orthography to represent an uppercase alpha bearing a rough breathing mark (dasia) and a circumflex accent (perispomeni) over the vowel. This character appears in ancient and liturgical Greek texts to indicate both aspiration at the start of a word and a rising-falling pitch contour on the long alpha. As a member of the Greek Extended block, it is typically employed in historical, philological, and ecclesiastical writings rather than in modern Greek, which uses monotonic accentuation. The dasia signals that the vowel is pronounced with an initial “h” sound, while the perispomeni denotes a circumflex tone in classical pronunciation.
