U+FF5B "｛" Fullwidth Left Curly Bracket Unicode Character

U+FF5B "｛" Fullwidth Left Curly Bracket is a typographic variant of the standard left curly bracket {, designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character, typically two East Asian character cells. It is part of the Halfwidth and Fullwidth Forms block, which was created to allow compatibility with legacy character sets that used fixed-width text, such as those found in older computer systems or certain Asian text environments. This fullwidth bracket is commonly used in East Asian text processing, where it pairs with its counterpart, the fullwidth right curly bracket U+FF5D, to denote sets, code blocks, or other groupings in a manner that aligns with the monospaced aesthetic of these scripts.
