title: MathJax font without italic
body: <p>I want to use <a href="http://www.mathjax.org" rel="noreferrer">MathJax</a> with a regular font, not italic. I tried to load different STIX fonts, but the symbols rendered with MathJax are always converted to italic. </p>
  
  <p>I've checked <a href="http://www.stixfonts.org/STIXfaq.html" rel="noreferrer">STIX font FAQ page</a> and it is supposed to have a regular version, but I can't figure out how to use it with Mathjax.</p>
