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]
Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment.
Geometric Shapes Extended. Halfwidth and Fullwidth Forms. Miscellaneous Symbols and Arrows (Unicode block) includes more geometric shapes. Miscellaneous Symbols and Pictographs (Unicode block) includes several geometric shapes of different colors. Mathematical operators and symbols in Unicode. Symbols for Legacy Computing.
Without proper rendering support, you may see question marks, boxes, or other symbols. Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters. They consist primarily of vulgar fractions and Roman numerals. In addition to the characters in the ...
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
Wingdings. Wingdings is a TrueType dingbat font included in all versions of Microsoft Windows from version 3.1 [ 4] until Windows Vista/Server 2008, and also in a number of application packages of that era. [ 5] The Wingdings trademark is owned by Microsoft, [ 4] and the design and glyph order was awarded U.S. Design Patent D341848 in 1993. [ 6]
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.
