U+F923 "藍" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+F923 "藍" CJK Compatibility Ideograph-# is a compatibility ideograph included in the Unicode standard to represent a variant form of a Chinese character, specifically a version of the character for "blue" or "indigo" that appears in legacy East Asian character sets, such as those used in older Japanese or Korean encoding systems. It belongs to the CJK Compatibility Ideographs block, which contains characters that duplicate shapes from existing CJK Unified Ideographs but are encoded separately to preserve roundtrip conversion with these legacy standards. This particular character is a compatibility version of the standard CJK character U+85CD "藍", and its use is generally discouraged in modern text, as the unified ideograph is preferred for consistent representation. Instead, U+F923 serves primarily as a compatibility mapping for data interchange with older systems.
