* Pulled in MathJax 1.1 (minus the 112 megabytes of PNG "fonts") * Pulled in some of <https://en.wikipedia.org/wiki/User:Nageh/mathJax> bits for initialization This doesn't currently override PNG images, but does replace the text-form if you configure it.

*
|
|
* MathJax/extensions/TeX/unicode.js
|
|
*
|
|
* Implements the \unicode extension to TeX to allow arbitrary unicode
|
|
* code points to be entered into the TeX file. You can specify
|
|
* the height and depth of the character (the width is determined by
|
|
* the browser), and the default font from which to take the character.
|
|
*
|
|
* Examples:
|
|
* \unicode{65} % the character 'A'
|
|
* \unicode{x41} % the character 'A'
|
|
* \unicode[.55,0.05]{x22D6} % less-than with dot, with height .55 and depth 0.05
|
|
* \unicode[.55,0.05][Geramond]{x22D6} % same taken from Geramond font
|
|
* \unicode[Garamond]{x22D6} % same, but with default height, depth of .8,.2
|
|
*
|
|
* Once a size and font are provided for a given conde point, they need
|
|
* not be specified again in subsequent \unicode calls for that character.
|
|
* Note that a font list can be given, but Internet Explorer has a buggy
|
|
* implementation of font-family where it only looks in the first
|
|
* available font and if the glyph is not in that, it does not look at
|
|
* later fonts, but goes directly to the default font as set in the
|
|
* Internet-Options/Font panel. For this reason, the default font list is
|
|
* "STIXGeneral,'Arial Unicode MS'", so if the user has STIX fonts, the
|
|
* symbol will be taken from that (almost all the symbols are in
|
|
* STIXGeneral), otherwise Arial Unicode MS is tried.
|
|
*
|
|
* To configure the default font list, use
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* TeX: {
|
|
* unicode: {
|
|
* fonts: "STIXGeneral,'Arial Unicode MS'"
|
|
* }
|
|
* }
|
|
* });
|
|
*
|
|
* The result of \unicode will have TeX class ORD (i.e., it will act like a
|
|
* variable). Use \mathbin, \mathrel, etc, to specify a different class.
