U+1F1D "Ἕ" Greek Capital Letter Epsilon with Dasia and Oxia Unicode Character

U+1F1D "Ἕ" Greek Capital Letter Epsilon with Dasia and Oxia is a precomposed character used in ancient Greek polytonic orthography, combining an uppercase epsilon with two diacritical marks: the dasia, which represents a rough breathing sound similar to an 'h' sound, and the oxia, an acute accent indicating a high pitch tone on that vowel. This character appears in classical and Byzantine Greek texts where precise pronunciation, including syllable stress and breathy onset, was recorded, though it is rarely encountered in modern Greek, which uses simpler monotonic orthography. It occupies the Unicode block Greek Extended and is historically significant for the study of ancient linguistics and textual criticism.
