U+1F38 "Ἰ" Greek Capital Letter Iota with Psili Unicode Character
U+1F38 "Ἰ" Greek Capital Letter Iota with Psili is a precomposed character used in the polytonic orthography of Ancient Greek, representing the capital letter iota combined with a psili, a diacritical mark that historically indicates the absence of the rough breathing sound (aspiration) at the start of a word. This character is part of the Greek Extended Unicode block and is employed primarily in scholarly and liturgical texts to accurately render classical Greek inscriptions and early manuscripts where such breathing marks were standard. Its inclusion in the Unicode standard facilitates the precise digital representation of ancient Greek, ensuring that the subtle phonetic distinctions of the language are preserved in modern computer systems and typography.
