U+F9FF "刺" CJK Compatibility Ideograph-# Unicode Character

U+F9FF "刺" CJK Compatibility Ideograph-# is a compatibility ideograph that represents a variant or duplicate form of the standard Chinese/Japanese character "剌" (meaning to pierce, stab, or kill), but it is encoded in the Compatibility Ideographs block specifically to preserve roundtrip compatibility with older character set standards like the Korean KS X 1001 or Japanese JIS X 0208. Despite its similarity to the unified character, this code point is not recommended for general use in modern text because it is a compatibility form that duplicates an already existing standard character, and its primary purpose is to allow for the exact mapping of legacy encoded text without data loss. In practice, it often appears in historical documents or electronically migrated data where the original encoding used this specific variant glyph.
