0x301B

0x301B refers to the Unicode code point U+301B, located in the CJK Symbols and Punctuation block. The glyph is a bracket-like punctuation mark used in East Asian typography and can vary in appearance depending on the font. In Japanese and Chinese texts, such marks may appear in conjunction with other brackets and quotes, and their exact role can differ between horizontal and vertical writing.

In terms of encoding, U+301B is represented in UTF-8 as the three-byte sequence E3 80 9B. In UTF-16 it is 0x301B, and in UTF-32 it is 0x0000301B. The code point’s inclusion reflects Unicode’s effort to document a broad range of punctuation used in East Asian typographic traditions.

The character is not commonly used in modern Western typography, but it is part of a family of related punctuation marks in the same Unicode block. Related symbols include other corner and bracket-like marks such as the Left/Right Tortoise Shell Brackets (U+3014–U+3017) and the Corner Brackets (U+300C/U+300D). These marks support traditional punctuation practices in East Asian texts and are of interest mainly to linguists, typographers, font designers, and software dealing with East Asian typesetting and input methods.
