U+0478 "Ѹ" Cyrillic Capital Letter Uk Unicode Character
Unicode Version 17.0
Ѹ
U+0478 "Ѹ" Cyrillic Capital Letter Uk is a historical ligature from the early Cyrillic script, formed by combining the letters О (O) and У (U) to represent the diphthong or vowel sound /u/ in Old Church Slavonic. This character, alongside its lowercase counterpart ѹ (U+0479), was used primarily in medieval manuscripts and printed texts before being gradually replaced by the single letter У in modern Cyrillic alphabets. Today, Ѹ is retained in Unicode primarily for scholarly purposes, such as the transcription and representation of ancient Slavic texts, and it is rarely encountered in contemporary writing.
