U+0418 "И" Cyrillic Capital Letter I Unicode Character

U+0418 "И" Cyrillic Capital Letter I is a letter used in the Cyrillic script, representing the vowel sound /i/ in languages such as Russian, Bulgarian, and Serbian. It is visually distinct from the Latin letter "N" due to its symmetrical, two-stroke diagonal form, and it often appears as a direct counterpart to the Latin "I" in transliteration. In Russian, this letter is the tenth character of the alphabet and serves a key role in both native vocabulary and loanwords, making it a fundamental component of written communication in many Slavic and non-Slavic languages that use Cyrillic.
