U+1FDF "῟" Greek Dasia and Perispomeni Unicode Character
U+1FDF "῟" Greek Dasia and Perispomeni is a combining diacritical mark used in ancient and polytonic Greek orthography, representing a combination of a rough breathing mark (dasia) and a circumflex accent (perispomeni). This character was historically employed to indicate both an initial aspirated sound and a rising then falling pitch on a single vowel, typically in texts that preserve the classical pitch accent system. It appears in modern digital typography primarily for scholarly editions, liturgical texts, or linguistic studies of ancient Greek, where precise representation of prosody and phonetic nuance is required. The character is encoded in the Unicode block for Greek and Coptic, serving as a specialized tool for accurately rendering historical Greek writing without necessitating separate combining marks.
