title: How to disable emoticons in HTML fields?
body: <p>On my symfony2 application, I have a form and a textarea in this form. So when I try the form on my Xperia Z3 I can choose some emoticons and add them to the fields. </p>
  
  <p>When I submit the form and debug the form content in my textarea field I got something like that :</p>
  
  <pre><code>ðŸ˜�ðŸ˜‚ðŸ˜ŠðŸ˜±ðŸ�”ðŸ˜¨ðŸ�”ðŸ˜¨ðŸ˜�ðŸ˜‚ðŸ˜®ðŸ
  </code></pre>
  
  <p>So, my question is : </p>
  
  <ul>
  <li>Can we disable all emoticons on each cellphone (Android, IOS, WP...) keyboard ?</li>
  <li>Or there is a way to remove/replace this content in my controller ?</li>
  </ul>
  
  <p>Thanks</p>
