U+F921 "嵐" CJK Compatibility Ideograph-# Unicode Character

U+F921 "嵐" CJK Compatibility Ideograph-# is a compatibility ideograph from the CJK Compatibility Ideographs block, which was encoded for round trip compatibility with older character set standards like CNS 11643 rather than for general use in modern text. It corresponds to a variant or duplicate form of a CJK Unified Ideograph, typically representing the Chinese character "lan" with meanings related to fruit or color in historical contexts. This character is not recommended for new text since it duplicates the unified ideograph U+84DD or similar, and its use is primarily restricted to preserving legacy data or specific encoding environments.
