U+2AC8 "⫈" Superset of Above Tilde Operator Unicode Character

U+2AC8 "⫈" Superset of Above Tilde Operator is a mathematical symbol used in formal logic and set theory to denote that one set is a superset of another set, specifically with a tilde placed above the superset symbol to indicate a modification or additional relation, such as a superset that excludes or is relative to a particular condition. It belongs to the Supplemental Mathematical Operators block and is typically rendered as a single composite glyph, combining the standard superset sign with a tilde positioned directly above it. This character is distinct from the simpler superset symbols (U+2287 ⊇ or U+2283 ⊃) and is applied in advanced mathematical notation where precision about the nature of the superset relationship is required.
