U+2ACC "⫌" Superset of Above Not Equal To Unicode Character

U+2ACC "⫌" Superset of Above Not Equal To is a mathematical symbol that extends the standard set notation by visually combining a superset symbol (⊃) with a negation slash that crosses the not equal sign (≠) placed above it. This character is used in advanced set theory and logic to indicate that one set is a superset of another, but explicitly not equal to it, serving as a more precise alternative to writing "⊃" with a separate "≠" annotation. It belongs to the Supplemental Mathematical Operators block in Unicode, designed to provide compact representations for nuanced relational concepts in technical documents and academic texts.
