U+1FDE "῞" Greek Dasia and Oxia Unicode Character

Unicode Version 17.0

U+1FDE "῞" Greek Dasia and Oxia is a specialized diacritical mark used in the polytonic orthography of ancient Greek. It combines the dasia, which indicates a rough breathing or an initial "h" sound, with the oxia, a type of acute accent denoting a high pitch or stress on a vowel. This composite mark appears only over certain vowels and diphthongs in a very limited number of classical texts, where it simultaneously specifies both the presence of an initial aspirate and the tonal accent. Its inclusion in Unicode allows scholars and digital typographers to accurately represent historically significant Greek inscriptions and editions that require this precise combination of phonetic and tonal notation.
