title: angularjs date filter ignores apostrophe
body: <p>I would like to have date formatted like here on SO: "Feb 6, '14".</p>
  
  <p>I cannot put the apostrophe there before the number 14.</p>
  
  <p>I tried the following formatter strings:</p>
  
  <pre><code>{{model.since | date:'MMM&amp;nbsp;d,&amp;nbsp;\'yy'}}
  {{model.since | date:'MMM&amp;nbsp;d,&amp;nbsp;&amp;#39;yy'}}
  {{model.since | date:"MMM&amp;nbsp;d,&amp;nbsp;'yy"}}
  {{model.since | date:"MMM&amp;nbsp;d,&amp;nbsp;&amp;#39;yy"}}
  </code></pre>
  
  <p>The apostrophe is not displayed.</p>
  
  <p>How can I put the apostrophe there?</p>
