U+F909 "契" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+F909 "契" CJK Compatibility Ideograph-# is a compatibility ideograph included in the Unicode standard to represent a variant or simplified form of a CJK (Chinese, Japanese, and Korean) character from a legacy character set, primarily to facilitate round-trip conversion with older encoding systems rather than for general modern usage. Specifically, it corresponds to the character "契" which means a contract, agreement, or to carve, but its appearance and encoding location differ from the unified CJK character U+5951 used in contemporary text. This ideograph is classified under the CJK Compatibility Ideographs block, meaning it is preserved for compatibility with earlier standards like CNS 11643 or other national encoding schemes, and it is not recommended for use in new content due to potential duplication or misuse within the broader Unicode CJK framework.
