U+F905 "串" CJK Compatibility Ideograph-# Unicode Character

U+F905 "串" CJK Compatibility Ideograph-# is a compatibility ideograph included in the Unicode standard specifically to represent a variant form of the Chinese/Japanese character for "string" or "thread" (commonly written as U+4E32 "串") as used in certain historical or legacy character set mappings. Its primary purpose is to enable round-trip conversion with older East Asian encoding systems, such as CNS 11643 or JIS X 0213, where this specific glyph shape was standardized. In modern Unicode usage, this character is not typically recommended for new text, as the standard character "串" is preferred, but it remains part of the Compatibility Ideographs block to preserve data integrity when converting from older formats. The character visually resembles the standard "串" but may appear with slight stylistic differences depending on the font.
