U+531B "匛" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

U+531B "匛" CJK Unified Ideograph-# is a rare and archaic Chinese character, classified under the "CJK Unified Ideographs" block, which encodes characters used in Chinese, Japanese, Korean, and Vietnamese writing. Its composition consists of the radical "匚" (a box-like enclosure) and the phonetic component "九" (meaning nine), suggesting it originally represented an ancient term or variant related to containers or measurement, though it is no longer in common use in modern East Asian languages. The character is primarily of interest to scholars of historical scripts, palaeography, or those studying obscure lexical entries in classical dictionaries, as it appears in some old character collections but lacks a well-defined, widely recognized modern meaning or usage.
