U+F9C2 "蓼" CJK Compatibility Ideograph-# Unicode Character

U+F9C2 "蓼" CJK Compatibility Ideograph-# is a compatibility ideograph primarily used in East Asian text processing, corresponding to a variant or duplicate of a standard CJK Unified Ideograph for a specific character. It was included in Unicode's Compatibility Ideographs block to facilitate round trip conversion from older encoding standards, such as certain Japanese Shift JIS or Korean KS X 1001 implementations, where this form was treated as a distinct character. In practice, U+F9C2 represents the same underlying Chinese character as its unified counterpart, but it is flagged for compatibility rather than general use, and its appearance can vary by font and region.
