U+A66D "ꙭ" Cyrillic Small Letter Double Monocular O Unicode Character

Unicode Version 17.0

U+A66D "ꙭ" Cyrillic Small Letter Double Monocular O is a rare glyph used in historical Church Slavonic manuscripts, where it represents a scribal abbreviation or a decorative ligature rather than a distinct phonetic value. It consists of two interlocked “O” shapes, resembling a horizontal figure eight or spectacles, and is classified within the Cyrillic Extended B block. This character was added to the Unicode standard in 2005 to support the accurate digital preservation of medieval Slavic texts, where it often appears in place names or religious terminology. Its use is strictly orthographic and not part of any modern Cyrillic alphabet, making it a specialized typographic curiosity for linguists, historians, and digital archivists studying early Cyrillic writing traditions.
