title: findText find something containing a quote
body: <p>I have a script that takes the current document and looks for a user defined string using findText. If that string contains a quote (like: Bob's Burgers). findText does not find it. I know it uses regular expressions, but I cannot figure out how to format the expression so it finds this properly. </p>
  
  <p>code example:</p>
  
  <pre><code>var target = "Bob's Burgers";
  var body = DocumentApp.getActiveDocument().getBody();
  
  try
  {
      var searchResult = body.findText(target);
      //does not find the text. But can find Bob easily.
  }
  catch(e) { ...}
  </code></pre>
