U+1F3B "Ἳ" Greek Capital Letter Iota with Dasia and Varia Unicode Character

U+1F3B "Ἳ" Greek Capital Letter Iota with Dasia and Varia is a precomposed polytonic Greek character used primarily in ancient and liturgical texts to represent the Greek letter iota with a rough breathing mark (dasia, indicating an 'h' sound) and a grave accent (varia, indicating a low or falling pitch). This specific combination provides a phonetic and diacritical accuracy essential for classical and religious writing, though it is rarely encountered in modern Greek, which no longer uses such accents or breathings. The character is encoded in the Unicode Greek Extended block, allowing it to be correctly displayed and processed in digital environments that support historic Greek orthography.
