U+F946 "牢" CJK Compatibility Ideograph-# Unicode Character

U+F946 "牢" CJK Compatibility Ideograph-# is a compatibility ideograph that represents a variant form of the standard CJK (Chinese, Japanese, and Korean) character for "牢" (láo), which means "prison" or "stable" in Chinese. This character falls within the CJK Compatibility Ideographs block, a set of characters encoded specifically to maintain round-trip compatibility with earlier character set standards, such as those used in legacy Japanese, Chinese, or Korean encoding systems. Its inclusion allows for the preservation of original text formatting and character forms without forcing a conversion to a more common or simplified glyph. The "牢" variant typically features minor graphical differences in stroke arrangement compared to its standard counterpart, though it shares the same semantic meaning and usage in historical or specialized documents.
