title: CakePHP: How to use a AwesomeFont icon in submit()?
body: <p>I'd like to use an <a href="http://fontawesome.io/icons/" rel="nofollow noreferrer">Font Awesome icon</a> in a submit button. I tried:</p>
  
  <pre><code>&lt;?= $this-&gt;Form-&gt;submit('&lt;i class="fa fa-save fa-2x"&gt;&lt;/i&gt;', ['escape' =&gt; false]) ?&gt;
  </code></pre>
  
  <p>But it doesn't work. How to do?</p>
