U+A67B "ꙻ" Combining Cyrillic Letter Omega Unicode Character

U+A67B "ꙻ" Combining Cyrillic Letter Omega is a diacritical mark used in historical Church Slavonic texts, designed to be placed above or attached to a base Cyrillic letter to modify its pronunciation or indicate a specific grammatical or scribal feature. This combining character represents a form of the Cyrillic omega, a letter derived from the Greek omega, and its primary function is to denote a broader or more open vowel sound, often in contexts influenced by liturgical or palaeographic conventions. It belongs to the Cyrillic Extended-B block and is rarely encountered outside specialized academic, religious, or digital typography projects focusing on old Slavic manuscripts and orthographic reconstruction.
