More browsers and Web sites are targeting a Unicode solution which is described below, but workarounds may still be needed for older browsers.
The following Unicode fonts include a comprehensive set of mathematical characters and are free for academic use.
The following browsers have the most consistent results
Mathematical & Logical Symbol Test: ∀OS (year(OS) ≥ 2001 | ∃Font ∋ (∛, ∬,≈))
Internet Explorer for Windows does not display mathematical symbols by default. Users who prefer Internet Explorer for Windows should set the Latin font to Arial Unicode MS or some other Unicode script with phonetic symbol support.
Internet Explorer for Macintosh may not support all mathematical symbols.
For text documents, the following is recommended.
Use the Windows Character Map to insert mathematical symbols.
Use the Macintosh Character Palette to mathematical symbols
No matter which method you use to create the document, the HTML page must be declared as a Unicode page with the following meta-tag.
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
...
</head>
Although it is generally not recommended to specify fonts for a language, it should be done for mathematica characters in order to force Internet Explorer to use the correct display display fonts.This can be done either via CSS styles or via the FONT tag.
Below is the CSS style class listing suggested font specifications.
.math {font-family: "Chrysanthi Unicode ", "Times New Roman", "Apple Symbols","Arial Unicode MS"}
Chrysanthi (Chryʃsanþi) is a freeware font with a very large set of symbol fonts included. Arial Unicode MS comes from Microsoft while Apple Symbols is provided by Apple.
The Times New Roman font on Windows and in newer Macs does include the basic Greek alphabet.
If you can use either the Windows Character Map or the Macintosh Character Palette with Dreamweaver, Notepad (Win), Unipad (Win) or BBEdit (Mac) to insert mathematical symbols directly into the HTML.
However, you may get uneven results between browsers.
You can you can substitute numeric entity codes for the mathematical symbosl. For example:
See Alan Wood's Mathematical Operator Unicode table for other common symbols
You can use the <sup></sup> tag to create super script text and <sub></sub> to create sub-script text. See examples below:
Code: x<sup>x+1</sup>
Result: xx+1
Code: x<sub>i+1</sub>
Result: xi+1
See the Superscript page for additional options.
Math ML is an XML language designed to present complex equations. Math ML support has been implemented into some Windows browsers, but not Macintosh browsers (only Firefox for Mac has partial support).
For now it is recommended that:
The following fonts are availble free for educational use and include most encoded mathematical and technical symbols.
