U+2983 "⦃" Left White Curly Bracket Unicode Character

U+2983 "⦃" Left White Curly Bracket is a typographical symbol classified under the Miscellaneous Mathematical Symbols-B block, designed to function as a left-opening white or open brace variant. It is visually distinct from the standard curly bracket by its hollow, unfilled appearance, making it useful in mathematical notation and formal logic to denote set membership, grouping, or specialized syntactic structures where a lighter visual weight is desired. This character complements its paired counterpart, the Right White Curly Bracket (U+2984), and is often applied in academic typesetting, particularly in Z notation and other formal specification languages, to avoid confusion with ordinary braces.
