U+6D03 "洃" CJK Unified Ideograph-# Unicode Character

U+6D03 "洃" CJK Unified Ideograph-# is a Chinese character used in written Chinese, Japanese, and Korean, though it is quite rare and not commonly employed in modern everyday texts. Its original meaning is associated with the concept of soot or ash, particularly referencing the fine, dark particles produced by burning, and it has historically appeared in specialized or classical literary contexts rather than in common vocabulary. The character combines the water radical on the left, indicating a semantic link to liquids or washing, with a phonetic component on the right that provides a clue to its pronunciation, which in Standard Mandarin is read as "huī." Overall, "洃" represents a minor but illustrative example of the vast CJK unified ideograph block, which encompasses thousands of characters sharing written heritage across East Asian languages.
