U+2AC4 "⫄" Superset of or Equal to with Dot Above Unicode Character
Unicode Version 17.0
⫄
U+2AC4 "⫄" Superset of or Equal to with Dot Above is a mathematical operator used in set theory and formal logic to denote that one set is a superset of or equal to another, with an additional dot placed above the symbol to indicate a specific, often more nuanced, relational or typographical variant. This character falls within the Supplemental Mathematical Operators block and is designed for use in precise technical notation, where the dot above may signify a conditional or functional property within larger expressions. Its inclusion in Unicode allows for consistent representation across digital platforms, ensuring that advanced mathematical texts and software can display the symbol without ambiguity.
