U+1F2C "Ἤ" Greek Capital Letter Eta with Psili and Oxia Unicode Character

U+1F2C "Ἤ" Greek Capital Letter Eta with Psili and Oxia is a precomposed glyph used in polytonic Greek orthography, combining the capital letter eta (Η) with the psili diacritic, indicating a smooth breathing mark, and the oxia diacritic, representing an acute accent. This character historically appears in ancient and liturgical Greek texts to denote a specific pronunciation where the vowel eta is both unaspirated at the beginning of a word and carries a high pitch or stress. As part of the Greek and Coptic block in Unicode, it serves to preserve the rich accentual and breathing system of classical Greek typography, allowing modern digital representation of scholarly, religious, or linguistic works that require precise diacritic combinations.
