U+2DFF "ⷿ" Combining Cyrillic Letter Iotified Big Yus Unicode Character
Unicode Version 17.0
ⷿ
U+2DFF "ⷿ" Combining Cyrillic Letter Iotified Big Yus is a historical diacritic mark used in early Cyrillic manuscripts and liturgical texts to represent a nasalized vowel sound, specifically the iotified version of the big yus (Ѫ, Ѭ). This combining character is placed above or attached to a base Cyrillic letter to modify its pronunciation, reflecting a phonetic feature of Old Church Slavonic that involved nasalization. Its inclusion in Unicode allows for the accurate digital representation of medieval Slavic writing, preserving the orthographic nuances of texts where such a character was employed to indicate the combination of a preceding iotated vowel with a nasalized back vowel.
