U+FF3D "］" Fullwidth Right Square Bracket Unicode Character

U+FF3D "］" Fullwidth Right Square Bracket is a typographic variant of the standard right square bracket designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character, typically twice the width of an ASCII bracket. It is part of the Halfwidth and Fullwidth Forms block in Unicode, intended for use in East Asian text where uniform character width is essential for alignment and readability, such as in monospaced text or mixed-script documents. This character is commonly employed in programming or markup contexts within Japanese or Chinese environments, where it serves as a closing delimiter in arrays, indices, or other bracket pairs, ensuring visual consistency with other fullwidth punctuation and characters.
