U+F991 "撚" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+F991 "撚" CJK Compatibility Ideograph-# is a compatibility ideograph originating from the CJK Unified Ideographs block, specifically part of a set of characters that were included in Unicode to maintain round-trip compatibility with older East Asian character encoding standards, such as those used in legacy systems and certain vendor-specific character sets. This particular character represents a variant or duplicate of a standard CJK unified ideograph, typically one that had a distinct encoding in earlier standards like JIS or CNS 11643, but it is not intended for general use in modern text, as modern systems prefer the unified version. The "#" in its name indicates that it is a compatibility ideograph, and its usage is discouraged in favor of its corresponding unified counterpart to promote consistency in digital text processing.
