Unicode Block - Enclosed CJK Letters and Months

Enclosed CJK Letters and Months is a collection of symbols that wraps Chinese, Japanese, and Korean characters or month names inside circles, parentheses, or other enclosures, primarily used for compatibility with legacy East Asian character sets. It includes circled forms of Hangul syllables, parenthesized ideographs, and circled or parenthesized representations of the months, such as ㋀ for January or ㋿ for December, alongside a few additional enclosed numerals and symbols. These characters serve practical purposes in lists, calendars, and annotated text, though many have been largely superseded by modern typographic methods, yet they remain encoded for data interchange with older systems.
