U+3203 "㈃" Parenthesized Hangul Rieul Unicode Character

U+3203 "㈃" Parenthesized Hangul Rieul is a CJK compatibility ideograph that represents the Korean consonant "rieul" (equivalent to the letter ᄅ in Hangul) enclosed within parentheses. It belongs to the "Enclosed CJK Letters and Months" block and was primarily designed for vertical text layout in older East Asian computing environments, allowing the consonant to be used as a standalone marker or label, such as in lists or annotations. In modern usage, it is rarely encountered in standard Korean text, as contemporary typographic systems rely on regular parentheses and Hangul jamo for similar purposes.
