U+2AD0 "⫐" Closed Superset Unicode Character
Unicode Version 17.0
⫐
U+2AD0 "⫐" Closed Superset is a mathematical symbol belonging to the Supplemental Mathematical Operators block, representing a superset relation where the opening side is closed off, often used in set theory and formal logic to denote a non-strict superset that is not an open relation. In contrast to the standard "superset of" sign, the closed variant indicates that the superset may include the possibility of equality between the two sets, though its specific usage can vary by context. This character is uncommon in everyday text but appears in specialized academic and technical writing to express precise relational constraints between sets or categories.
