U+1F88 "ᾈ" Greek Capital Letter Alpha with Psili and Prosgegrammeni Unicode Character

U+1F88 "ᾈ" Greek Capital Letter Alpha with Psili and Prosgegrammeni is a precomposed character from the Greek Extended block, used in polytonic Greek orthography to represent the vowel alpha with a smooth breathing mark, known as psili, and an attached iota subscript, referred to as prosgegrammeni in its capital form. This character typically appears at the beginning of a word in ancient or liturgical Greek texts, indicating that the alpha is pronounced without an aspiration while also requiring a following long iota sound, though the iota itself is not written as a full letter but as a small line beneath the capital alpha.
