Mathematical operators and symbols in Unicode

Blackboard at the Laurent Schwartz Center for Mathematics, École Polytechnique

The Unicode Standard encodes almost all standard characters used in mathematics.[1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation.[1] 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".[2][3]

Dedicated blocks

Mathematical Operators block

The Mathematical Operators block (U+2200–U+22FF) contains characters for mathematical, logical, and set notation.

The Mathematical Alphanumeric Symbols block (U+1D400–U+1D7FF) contains Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The "holes" in the alphabetic ranges are filled by previously defined characters in the Letter like Symbols block shown below.
