U+F9FD "什" CJK Compatibility Ideograph-# Unicode Character

U+F9FD "什" CJK Compatibility Ideograph-# is a compatibility ideograph located in the CJK Compatibility Ideographs block, representing a variant or unified form of the standard Chinese character for the word "what" or "how" (often corresponding to the simplified character 什么). It was encoded specifically for round-trip compatibility with older East Asian character sets, such as those used in legacy Japanese or Korean encoding standards, ensuring that text converted from those systems retains its original appearance. Unlike ordinary CJK Unified Ideographs, this character is not intended for new text creation and is primarily preserved for historical or archival data interchange purposes.
