U+3223 "㈣" Parenthesized Ideograph Four Unicode Character
U+3223 "㈣" Parenthesized Ideograph Four is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the number four enclosed within parentheses, designed primarily for use in vertical text layouts or as a typographic convenience in East Asian scripts. This character falls within the Enclosed CJK Letters and Months block and was encoded in Unicode version 1.1 to facilitate compatibility with pre-existing character sets, often appearing in lists, calendars, or numbering systems where a parenthesized numeral is required. Its visual form combines the standard Chinese ideograph for four (四) with surrounding parentheses, aligning with similar characters for other digits to provide a consistent and compact representation in digital text.
