U+F993 "煉" CJK Compatibility Ideograph-# Unicode Character

U+F993 "煉" CJK Compatibility Ideograph-# is a compatibility ideograph found in the CJK Compatibility Ideographs block, which was encoded primarily to preserve round-trip compatibility with older East Asian character set standards such as CNS 11643 and KPS 9566. It represents a specific glyph form or character variant that corresponds to a unified CJK character, typically U+7149 "煉" (meaning "to refine" or "to smelt"), but is kept separate in Unicode to avoid information loss when converting from legacy encodings. This character is not intended for general use in modern text and is instead a legacy mapping artifact, often identified by the "#" symbol to denote its compatibility status.
