U+FA0B "廓" CJK Compatibility Ideograph-# Unicode Character

U+FA0B "廓" CJK Compatibility Ideograph-# is a rare or obsolete Chinese character classified under the "CJK Compatibility Ideographs" block, which was encoded primarily to maintain round-trip compatibility with older East Asian character set standards like JIS X 0208 and other legacy encoding systems. It represents a specific glyph that is typically a variant or duplicate of another standard CJK Unified Ideograph, but it is preserved in Unicode to ensure that text data converted from those older systems remains unchanged. This particular ideograph is not used in modern Chinese, Japanese, or Korean writing and exists mostly for historical data interchange, with its exact meaning and pronunciation often being obscure or undocumented in contemporary dictionaries.
