Mathematical operators and symbols in Unicode

Blackboard at the Laurent Schwartz Center for Mathematics, École PolytechniqueThe Unicode Standard encodes almost all standard characters used in mathematics. Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". Dedicated blocksMathematical Operators blockThe Mathematical Operators block (U+2200–U+22FF) contains characters for mathematical, logical, and set notation. Supplemental Mathematical Operators blockThe Supplemental Mathematical Operators block (U+2A00–U+2AFF) contains various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations. Mathematical Alphanumeric Symbols blockThe Mathematical Alphanumeric Symbols block (U+1D400–U+1D7FF) contains Latin and Greek letters and d
