U+2AD2 "⫒" Closed Superset or Equal To Unicode Character

U+2AD2 "⫒" Closed Superset or Equal To is a mathematical symbol used primarily in set theory and logic, where it denotes that one set is either a superset of or equal to another set, serving as a notational alternative to the more common "⊇" symbol. This character belongs to the Supplemental Mathematical Operators block, which includes various specialized relational operators designed for formal writing and typesetting in academic and technical documents. It is often employed in contexts requiring precise expression of subset and superset relationships, such as in proofs or algebraic structures, and is distinct from its open counterpart by the closed or filled appearance of the superset symbol.
