U+58F9 "壹" CJK Unified Ideograph-# is a Chinese character used primarily as the formal or financial variant of the numeral "one," intended to prevent alteration in legal, banking, and commercial documents where precision is critical. Its structure combines components suggesting "one" and "a pot" or "a vessel," and it is part of a set of complex, stroke-heavy characters traditionally employed in East Asian contexts to ensure that amounts cannot be easily changed by adding strokes, as would be possible with simpler numerals. The character is encoded in the CJK Unified Ideographs block of Unicode, reflecting its historical and ongoing significance in written Chinese, Japanese, and Korean.
