Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics. By providing uniformity over numerous mathematical articles and books, these conventions help to read mathematical formulas. Unicode now includes many such symbols. The rationale behind this is that it enables design and usage of special mathematical characters that include all necessary properties to differentiate from other alphanumerics, e.g. in mathematics an italic "A" can have a different meaning from a roman letter "A". Unicode originally included a limited set of such letter forms in its Letterlike Symbols block before completing the set of Latin and Greek letter forms in this block beginning in version 3.1. Unicode expressly recommends that these characters not be used in general text as a substitute for presentational markup; the letters are specifically designed to be semantically different from each other. Unicode does not include a set of normal serif letters in the set. Still they have found some usage on social media, for example by people who want a stylized user name. All these letter shapes may be manipulated with MathML's attribute mathvariant. The introduction date of some of the more commonly used symbols can be found in the Table of mathematical symbols by introduction date.
Tables of styled letters and digits
These tables show all styled forms of Latin and Greek letters, symbols and digits in the Unicode Standard, with the normal unstyled forms of these characters shown with a cyan background. The styled characters are mostly located in the Mathematical Alphanumeric Symbols block, but the 24 characters in cells with a pink background are located in the letterlike symbols block, for example, ℛ is at U+211B rather than the expected U+1D4AD which is reserved. In the code charts for the Unicode Standard, the reserved code points corresponding to the pink cell are annotated with the name and code point of the correct character. There are a few characters which have names that suggest that they should belong in the tables below, but in fact do not because their official character names are misnomers:
is in fact the Weierstrass p which was misnamed, but due to Unicode stability policies the official character name cannot be corrected.
Latin letters
The Unicode values of the characters in the tables below, except those shown with or index values of '–', are obtained by adding the base values from the "U+" header row to the index values in the left column.
Greek letters and symbols
The Unicode values of the characters in the tables below, except those shown with or index values of '–', are obtained by adding the base values from the "U+" header row to the index values in the left column.
