U+1F2D "Ἥ" Greek Capital Letter Eta with Dasia and Oxia Unicode Character

U+1F2D "Ἥ" Greek Capital Letter Eta with Dasia and Oxia is a precomposed character used in the polytonic orthography of ancient Greek to represent the long vowel eta combined with a rough breathing mark, known as dasia, and an acute accent, known as oxia, indicating that the syllable is both aspirated and carries a high pitch. This character is historically employed in scholarly editions of classical texts to denote specific pronunciation and accentuation patterns, such as at the beginning of a word like "Ἥλιος" meaning sun, where the rough breathing signals an initial /h/ sound and the acute marks the stressed syllable. As part of the Greek and Coptic block in Unicode, it allows digital preservation of these diacritical combinations without the need for separate combining marks, aiding accurate representation of ancient Greek typography.
