About this character
U+0410, Cyrillic capital letter A, is the first letter of the Cyrillic alphabet, representing the /a/ sound across Russian, Bulgarian, Serbian, and other Slavic languages. Its form derives directly from the Greek alpha, adopted during the ninth-century Cyrillic creation for Slavic liturgy. In typography, it often mirrors the Latin “A” but holds distinct Unicode codepoints, preventing automatic substitution in multilingual text. In programming, this character appears in identifiers and string data, particularly when handling Russian-language locales, requiring careful normalization. Designers use it to evoke Slavic authenticity in logos and signage, while writers depend on it for proper orthography, capitalization, and alphabetization in Cyrillic-based scripts.
