U+FFE2 "￢" Fullwidth Not Sign Unicode Character
Unicode Version 17.0
￢
U+FFE2 "￢" Fullwidth Not Sign is a typographic variant of the standard logical negation symbol (¬), designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character for proper alignment in East Asian text. It is encoded in the Halfwidth and Fullwidth Forms block and is often used in mathematical or logical notation to represent the "not" operation. When displayed, it appears as a horizontal line with a small downward hook at the right end, mirroring the regular not sign but with a fullwidth form factor.
