U+FE5B "﹛" Small Left Curly Bracket Unicode Character

U+FE5B "﹛" Small Left Curly Bracket is a typographic variant of the standard left curly bracket, designed as a narrower or smaller form for use in contexts where space is limited or where a more delicate appearance is desired. It belongs to the CJK Compatibility Forms block, which includes small forms of various punctuation marks and symbols tailored for compatibility with East Asian text layouts, particularly in vertical writing or alongside complex character grids. This character primarily serves as an opening brace in mathematical notation, programming, or textual enclosures, but its reduced size makes it less common in general-purpose English text.
