U+321A "㈚" Parenthesized Hangul Phieuph A Unicode Character

U+321A "㈚" Parenthesized Hangul Phieuph A is a CJK (Chinese, Japanese, and Korean) compatibility ideograph used primarily in legacy Korean text processing systems. It represents the Hangul syllable “피읖” (pieup) enclosed in parentheses, forming a single typographic unit that was historically employed in early computerized Korean character sets to denote a parenthesized consonant or phoneme. This character belongs to the Enclosed CJK Letters and Months block, which includes symbols designed for compatibility with pre existing standards, allowing older documents to display correctly in modern Unicode environments. Its usage is largely obsolete today, as current Korean text encoding relies on standard Hangul syllables and separate parentheses rather than precomposed combinations like this one.
