U+1F28 "Ἠ" Greek Capital Letter Eta with Psili Unicode Character
U+1F28 "Ἠ" Greek Capital Letter Eta with Psili is a character from the Greek extended block that represents the uppercase Greek letter Eta (Η) combined with a psili, a diacritical mark indicating a smooth breathing in ancient Greek, meaning that the vowel is pronounced without an initial aspirated "h" sound. This character is used in polytonic Greek orthography, which includes multiple diacritics to denote pronunciation, though it is rarely employed in modern Greek and appears primarily in scholarly texts, classical literature, or liturgical works that preserve historical accentuation and breathing marks. Its inclusion in Unicode ensures that digital representations of ancient Greek manuscripts remain accurate for linguists, historians, and theologians.
