title: Replace submit button value with ASCII character
body: <p>I'm trying to replace the "save" value of the submit button with an ASCII character code like <code>&amp;#151;</code> (&#151;), except it's displaying the literal code instead of its translation.</p>
  
  <pre><code>$("#myform").on("submit", function(){
      $("input#commit").attr('readonly', true).val("&amp;#151;");
  });
  </code></pre>
  
  <p>Yields a button like this:</p>
  
  <pre><code>[ &amp;#151; ]
  </code></pre>
  
  <p>I also tried <code>.prop('value', '&amp;#151;');</code> but same problem. Is this even possible?</p>
