title: Remove everything between two characters including the characters
body: <pre><code>string = "$hahahaha$hahahaha hello";
  </code></pre>
  
  <p>How can I remove everything between the 2 $'s and also the $'s so I end up with:</p>
  
  <pre><code>hahahaha hello
  </code></pre>
  
  <p>The $ could also be '@' or '*' or '&amp;' or '?'</p>
