U+A650 "Ꙑ" Cyrillic Capital Letter Yeru with Back Yer Unicode Character

U+A650 "Ꙑ" Cyrillic Capital Letter Yeru with Back Yer is a historical typographic variant used primarily in early Cyrillic manuscripts and printed texts, representing a combination of the letters Yeru (which itself is a digraph of Ъ and І) and the Back Yer (a reversed form of the Yer or hard sign). This character was employed in Old East Slavic and Church Slavonic orthography to denote a specific phonetic value or scribal convention, often appearing in words where the back yer vowel was stressed or lengthened. It is encoded in the Cyrillic Extended-B block of Unicode, intended for scholarly and paleographic transcription, and is not used in modern standard Cyrillic alphabets.
