U+FF3B "［" Fullwidth Left Square Bracket Unicode Character
Unicode Version 17.0
U+FF3B "［" Fullwidth Left Square Bracket is part of the CJK Compatibility and Halfwidth and Fullwidth Forms block, specifically encoded to provide a vertically symmetrical, double-width version of the standard ASCII left square bracket (U+005B) for use in East Asian typography, where monospaced characters occupy the same horizontal space as other fullwidth characters. It is typically rendered twice as wide as its halfwidth counterpart and finds common use in Japanese, Chinese, and Korean text processing, particularly within programming contexts or formatted documents that require consistent vertical alignment. This character ensures that brackets align properly with fullwidth letters, digits, and punctuation in environments such as terminal displays or legacy character encodings, while maintaining visual harmony in mixed-width text layouts.
