title: Convert a char to a String
body: <p>I want to convert a char to a String in the following way:</p>
  
  <pre><code>char aaa = '\uE001';
  </code></pre>
  
  <p>I want to obtain a string with the value of <code>"\uE001"</code> so I can use <code>substring(2)</code> to obtain only <code>"E001"</code>. Is that possible? Please help</p>
