U+A652 "Ꙓ" Cyrillic Capital Letter Iotified Yat Unicode Character

U+A652 "Ꙓ" Cyrillic Capital Letter Iotified Yat is a historical glyph from the early Cyrillic alphabet, representing a vowel sound that combined the iotation or palatalization of the letter "yat" with a preceding "I" sound, essentially a variant of the regular yat letter (Ѣ) used in certain Old Church Slavonic and early East Slavic manuscripts. This character, along with its lowercase counterpart ꙓ, was part of a complex system of letters that gradually fell out of use as the Cyrillic script evolved and simplified, particularly after the Russian orthography reform of 1918 which abolished the yat entirely. While rarely seen in modern texts, the iotified yat survives in scholarly editions of medieval Slavic documents and in specialized fonts designed for historical linguistic research.
