U+3228 "㈨" Parenthesized Ideograph Nine Unicode Character
Unicode Version 17.0
㈨
U+3228 "㈨" Parenthesized Ideograph Nine is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the number nine enclosed in parentheses, often used in East Asian contexts for ordered lists, calendar dates, or formal document numbering. It is part of a set of parenthesized ideographs from one to twenty that were historically included in Unicode mainly for compatibility with legacy character sets and older text systems in Japan and China, where such symbols facilitated concise notation in vertical text. The character combines the Chinese character for nine (九) with a pair of parentheses, visually aligning with other similar symbols in the block.
