U+A690 "Ꚑ" Cyrillic Capital Letter Tsse Unicode Character

U+A690 "Ꚑ" Cyrillic Capital Letter Tsse is part of the Cyrillic Extended-B block and was added to the standard in version 5.1, released in 2008, as a historic typographic ligature or digraph used primarily in Old Church Slavonic or early Cyrillic manuscripts. This character represents a composite letter combining the sounds of "ts" and "se," typically transcribed as "tsse" in modern transliteration, and it is rarely used in contemporary alphabets outside of scholarly or liturgical contexts. Its inclusion in Unicode ensures that researchers, linguists, and digital archivists can accurately preserve and reproduce medieval texts without resorting to workarounds.
