/*************************************************************
*
* 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 code 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.
