U+301A "〚" Left White Square Bracket Unicode Character

U+301A "〚" Left White Square Bracket is a punctuation mark used primarily in East Asian typography, particularly in Chinese, Japanese, and Korean writing systems. It resembles an open bracket but with a distinctive white, hollowed appearance, often employed alongside its matching right counterpart U+301B to enclose text, indicate quotations, or mark off specific sections in formal or decorative contexts. This character is part of the CJK Symbols and Punctuation block and is historically derived from traditional bracket forms used to denote vertical text layout or annotation in classical documents, though it also appears in modern digital texts for stylistic emphasis or to signal boundaries in specialized notation.
