U+A667 "ꙧ" Cyrillic Small Letter Soft Em Unicode Character

U+A667 "ꙧ" Cyrillic Small Letter Soft Em is a historical glyph used in early Church Slavonic manuscripts, representing a palatalized or soft version of the letter "M" that is no longer part of any modern Cyrillic alphabet. It belongs to the Cyrillic Extended-B block, which covers archaic letters added primarily for scholarly and liturgical text encoding. This specific character, with its distinct form featuring a tail or hook indicating softness, served a phonetic purpose in medieval Slavic writing before such distinctions were gradually lost or merged into other letters. Its inclusion in Unicode allows for accurate digital representation of ancient texts, helping linguists and historians preserve and analyze the original sounds and orthography of Early Cyrillic literature.
