U+F97E "量" CJK Compatibility Ideograph-# Unicode Character

U+F97E "量" CJK Compatibility Ideograph-# is a compatibility ideograph found in the CJK Compatibility Ideographs block, which represents the Chinese character meaning "quantity," "capacity," or "measure," often used in traditional contexts. It is encoded specifically for round-trip compatibility with older East Asian character encoding standards like CNS 11643 and Big5, where it was assigned a unique code point. This character is visually identical or nearly identical to its standard CJK Unified Ideograph counterpart U+91CF "量", but it is included in Unicode solely to preserve the exact mapping from these legacy systems without semantic distinction. Its primary purpose is to support the conversion and interchange of text from pre-Unicode systems, ensuring that documents encoded in those older standards can be accurately represented in Unicode without loss of information.
