U+F9C9 "柳" CJK Compatibility Ideograph-# Unicode Character

U+F9C9 "柳" CJK Compatibility Ideograph-# is a compatibility ideograph found in the CJK Compatibility Ideographs block, and it represents a variant form of the Chinese character for "willow" or "柳" (liǔ). This specific character was included in Unicode primarily to maintain roundtrip compatibility with older East Asian character encoding standards, such as those used in Japanese or Korean legacy systems, rather than for modern, active use. In practice, it is largely considered a duplicate of the standard CJK Unified Ideograph U+67F3 (柳) and is not recommended for use in contemporary text, as the unified ideograph is the preferred representation. Its inclusion helps preserve the fidelity of historical digital documents without altering their original encoded forms.
