title: mkdocs How to use German umlauts in combination with Mathjax?
body: <p>I want to type the following formula in mkdocs using Mathjax</p>
  
  <pre><code>$$\text{Volumenänderungsarbeit} &amp; L_\text{vol} = -\int p \,dV$$
  </code></pre>
  
  <p>The problem is the German umlaut ä that I am using. If I remove it, then everything is fine. I tried to replace it but it does not work.</p>
  
  <ul>
  <li>\text{Volumen{\"a}nderungsarbeit}</li>
  <li>\text{Volumen"anderungsarbeit} </li>
  <li>\text{Volumen}{\"a}\text{nderungsarbeit} </li>
  <li>\text{Volumen\"anderungsarbeit}</li>
  </ul>
