U+1FCF "῏" Greek Psili and Perispomeni Unicode Character

U+1FCF "῏" Greek Psili and Perispomeni is a combining diacritical mark used in ancient Greek polytonic orthography to represent a specific accentual and breathing combination. It combines the psili, which indicates a smooth breathing (absence of an aspirated 'h' sound) over an initial vowel or diphthong, with the perispomeni, a circumflex accent that denotes a high-pitched, then falling tone on a long vowel. This character is typically placed above a vowel letter in edited classical texts to precisely denote both the pronunciation and the historical tonal contour of the syllable. It is part of a standardized set of polytonic Greek characters in Unicode, supporting accurate typographic representation of older Greek scholarly and liturgical materials.
