title: Cannot get material-ui datepicker to work
body: <p>For some reason, I cannot get the <strong>material-ui</strong> datepicker to work. Every time the datepicker is rendered in React, the following error is thrown:</p>
  
  <blockquote>
    <p>RangeError: Format string contains an unescaped latin alphabet character <code>n</code></p>
  </blockquote>
  
  <p>I have created a stackblitz with just the datepicker (<a href="https://stackblitz.com/edit/react-6ma6xd?embed=1&amp;file=index.js" rel="noreferrer">https://stackblitz.com/edit/react-6ma6xd?embed=1&amp;file=index.js</a>) and even there the error shows up. What am I doing wrong? I think I followed all the instructions from the installation guide.</p>
