rendering Angstrom Symbol with Mathjax and sphinx

gistfile1.txt

MathJax doesn't directly support the Angstrom symbol, TeX's \AA.  This is painful in many 
fields, notably those that work with X-rays.

To use mathjax with the Sphinx documentation system, one would put 

    extensions = ['sphinx.ext.mathjax', ...]
    
in conf.py.  But this will not understand \AA as the Angstrom symbol.

The solution is to add a Mathjax configuration script to each HTML file produced by sphinx.  
To do this, put the following code in _templates/layout.html:

    {% extends "default/layout.html" %}

    {%- block extrahead %}
        <script type="text/x-mathjax-config"> MathJax.Hub.Config({
        "TeX": {Macros: {AA : "{\\unicode{x212B}}"}}, "HTML-CSS": {scale: 90}});
        </script>
    {% endblock %}


This will tell mathjax to use the unicode (version 6.0?  ISO Latin?) symbol for Angstrom.

If I put this code into the docstring for my .py file prior to the first use of \AA, MathJax now has Å in the HTML output:

Did you mean that we should write in conf.py the following snippet?

extensions = [ 'sphinx.ext.mathjax', ...]

rst_prolog = u"""\

.. only:: html

   :math:`\\require{mediawiki-texvc}`

"""    

I tried it, but the $\AA$ symbol was not rendered as expected, it was red \AA.

Meanwhile, there was a warning:
