title: How to create multiline textbox which shows apostrophe before each line
body: <p>I want a multiline textbox which shows apostrophes before and after each line.
  So that the textbox looks like:</p>
  
  <pre><code>" Hello this  "
  " is a funny  "
  " string test "
  </code></pre>
  
  <p>Or for example:</p>
  
  <pre><code>// This is
  // a muliline
  // comment.
  </code></pre>
  
  <p>Edit: These special characters must be readonly and if the user copies text from the textbox these characters should <strong>not</strong> be included.</p>
