U+F997 "聯" CJK Compatibility Ideograph-# Unicode Character

U+F997 "聯" CJK Compatibility Ideograph-# is a character from the CJK (Chinese, Japanese, and Korean) Compatibility Ideographs block, encoded primarily for round-trip compatibility with older East Asian character sets such as CNS 11643. It represents a variant form of the standard CJK Unified Ideograph for the Chinese character "連" or "联," which means "to connect" or "to link," but its usage in modern text is generally avoided in favor of its unified counterpart. This character is considered a compatibility ideograph, meaning it exists to preserve the exact representation of source text from legacy systems, though it may cause ambiguity in modern processing and is not recommended for new documents.
