U+1FC0 "῀" Greek Perispomeni Unicode Character

U+1FC0 "῀" Greek Perispomeni is a combining diacritical mark used in polytonic Greek orthography to represent the perispomene, a type of circumflex accent historically indicating a rising and then falling pitch on a long vowel or a diphthong. It is positioned above a base vowel character and, when combined, it specifies linguistic nuance rather than modern stress, as the perispomene primarily appears in ancient and liturgical texts. This character is distinct from the simple tonos accent used in modern monotonic Greek, serving instead as a critical element for accurately reproducing classical Greek pronunciation and textual tradition.
