title: jQuery ajax call in IE - encoding
body: <p>I have an ajax POST request with some data being passed to the server side. 
  This is all working nicely on all browsers, but in case I have some specific characters, it fails in IE9. For example, sending "John Smith" through POST works just fine, but if I try "Rafał Szukała" (please notice specific <em>l</em> letter) in IE9, the browser doesn't pass them properly so I end up with band server response. Mozilla's working fine with this string btw.</p>
  
  <p>Any ideas how this can be solved?</p>
