U+F957 "綾" CJK Compatibility Ideograph-# Unicode Character

U+F957 "綾" CJK Compatibility Ideograph-# is a compatibility ideograph included in the Unicode standard to represent a variant Japanese kanji form of the character traditionally written as 練 (with the same U+7DF4 encoding), meaning to knead, train, or practice. It belongs to the CJK Compatibility Ideographs block, which was encoded primarily to preserve the round-trip conversion fidelity of older character set standards like JIS X 0208, and in modern usage it is generally considered a duplicate or legacy form that should be avoided in favor of its unified counterpart.
