U+F931 "櫓" CJK Compatibility Ideograph-# Unicode Character

U+F931 "櫓" CJK Compatibility Ideograph-# is a specialized glyph included in the Unicode standard's CJK Compatibility Ideographs block, which was created primarily to preserve round trip compatibility with older East Asian character set standards such as CNS 11643. This particular character corresponds to the CJK Unified Ideograph U+2F931, meaning it represents the same underlying Chinese character as its unified counterpart but is encoded in the Compatibility block to maintain exact mapping from legacy encodings. Its meaning is the same as that of the unified ideograph, typically associated with the concept of "abrupt" or "startled" in Chinese and Japanese, though its use in modern digital text is rare due to the prevalence of the unified version in standard encoding.
