U+F967 "不" CJK Compatibility Ideograph-# Unicode Character

U+F967 "不" CJK Compatibility Ideograph-# is a compatibility ideograph that represents a variant form of the common Chinese character 不 (meaning "not" or "no"), but it exists in the Unicode standard specifically to preserve the shape and encoding used in earlier East Asian character sets, such as those found in legacy CJK (Chinese, Japanese, Korean) computing systems. This character falls under the CJK Compatibility Ideographs block, which was included to ensure round-trip conversion fidelity with older standards like CNS 11643 or JIS X 0208, rather than for modern use in typical text. Its visual form may appear slightly different from the standard character in some fonts, reflecting a historical glyph variant.
