U+1F81 "ᾁ" Greek Small Letter Alpha with Dasia and Ypogegrammeni Unicode Character
U+1F81 "ᾁ" Greek Small Letter Alpha with Dasia and Ypogegrammeni is a precomposed character used in classical polytonic Greek orthography, combining a small alpha with a rough breathing mark (dasia, indicating an initial /h/ sound) and an iota subscript (ypogegrammeni, representing a long vowel sound with an underlying iota). It appears in ancient texts to denote the aspirated beginning of a word, often in forms of verbs or nouns, and is typically encountered in scholarly editions of Greek literature, where the subscript iota is written below the letter rather than beside it, as in the regular iota adscript. This character belongs to the Greek Extended block in Unicode, encoding a specific grammatical and phonetic nuance that is essential for accurate rendering of ancient Greek in digital formats.
