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. These also may be used to differentiate between concepts that share a letter in a single problem.

Miscellaneous Symbols is a Unicode block (U+2600–U+26FF) containing glyphs representing concepts from a variety of categories: astrological, astronomical, chess, dice, musical notation, political symbols, recycling, religious symbols, trigrams, warning signs, and weather, among others.

Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.

Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF, which contains various common symbols which are related to and used in the various technical, programming language, and academic professions. For example:

In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but is nonetheless available for use as part of a text.

<span class="mw-page-title-main">Mathematical operators and symbols in Unicode</span>

The 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".

Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. These can be used for filling regions of the screen and portraying drop shadows. Its block name in Unicode 1.0 was Blocks.

Supplemental Arrows-B is a Unicode block containing miscellaneous arrows, arrow tails, crossing arrows used in knot descriptions, curved arrows, and harpoons.

Miscellaneous Mathematical Symbols-B is a Unicode block containing miscellaneous mathematical symbols, including brackets, angles, and circle symbols.

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.

Miscellaneous Symbols and Arrows is a Unicode block containing arrows and geometric shapes with various fills, astrological symbols, technical symbols, intonation marks, and others.

Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.

Miscellaneous Symbols and Pictographs is a Unicode block containing meteorological and astronomical symbols, emoji characters largely for compatibility with Japanese telephone carriers' implementations of Shift JIS, and characters originally from the Wingdings and Webdings fonts found in Microsoft Windows.

Arabic Mathematical Alphabetic Symbols is a Unicode block encoding characters used in Arabic mathematical expressions.

Enclosed CJK Letters and Months is a Unicode block containing circled and parenthesized Katakana, Hangul, and CJK ideographs. Also included in the block are miscellaneous glyphs that would more likely fit in CJK Compatibility or Enclosed Alphanumerics: a few unit abbreviations, circled numbers from 21 to 50, and circled multiples of 10 from 10 to 80 enclosed in black squares.

Musical Symbols is a Unicode block containing characters for representing modern musical notation. Fonts that support it include Bravura, Euterpe, FreeSerif, Musica and Symbola. The Standard Music Font Layout (SMuFL), which is supported by the MusicXML format, expands on the Musical Symbols Unicode Block's 220 glyphs by using the Private Use Area in the Basic Multilingual Plane, permitting close to 2600 glyphs.

Yijing Hexagram Symbols is a Unicode block containing the 64 hexagrams from the I Ching.

Emoticons is a Unicode block containing emoticons or emoji. Most of them are intended as representations of faces, although some of them include hand gestures or non-human characters.

Variation Selectors is the block name of a Unicode code point block containing 16 variation selectors used to specify a glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1, VS2, VS3, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively.

Supplemental Symbols and Pictographs is a Unicode block containing emoji characters. It extends the set of symbols included in the Miscellaneous Symbols and Pictographs block. It also includes Typikon symbols.
