U+FF23 "Ｃ" Fullwidth Latin Capital Letter C Unicode Character

U+FF23 "Ｃ" Fullwidth Latin Capital Letter C is a typographic variant of the standard Latin capital C designed to occupy the same fixed width as CJK (Chinese, Japanese, and Korean) characters, allowing it to align neatly in monospaced East Asian text. It belongs to the Halfwidth and Fullwidth Forms block and is visually identical to a standard uppercase C but occupies a full character cell, making it useful for preserving uniform spacing in mixed Latin and CJK documents or for decorative effects in plain text environments.
