U+2AC7 "⫇" Subset of Above Tilde Operator Unicode Character
Unicode Version 17.0
⫇
U+2AC7 "⫇" Subset of Above Tilde Operator is a mathematical symbol used in formal logic and set theory to denote that one set or element is a subset of another, with the distinguishing feature that the tilde operator is placed above the subset symbol rather than beside it. This specific orientation serves a specialized purpose in mathematical notation, often indicating a particular relationship or constraint within complex expressions where the typical subset sign might be ambiguous. The character is part of the Supplemental Mathematical Operators block, designed to provide precise typographic representation for advanced mathematical texts and publications.
