Supplemental Mathematical Operators is a Unicode block containing various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.
The Supplemental Mathematical Operators block has eight variation sequences defined for standardized variants.
[3][4] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font): The following Unicode-related documents record the purpose and process of defining specific characters in the Supplemental Mathematical Operators block:
