title: Another JQuery encoding problem, on IE
body: <p>I'm coding an italian website where I need to validate some input data with an xhr call.
  My code for the ajax request's like this (I'm using JQuery 1.3.2):</p>
  
  <pre><code> $.ajaxSetup({
      type: "POST",
      timeout: 10000,
      contentType: "application/x-www-form-urlencoded; charset=iso-8859-1"        
  }); 
  
  
   $.ajax({
      url: "ajaxvalidate.do",
      data: {field:controlInfo.field,value:controlInfo.fieldValue},
      dataType: "json",
      complete: function() {
          //
      },
      success: function(msg) {
          handleAsyncMsg(controlInfo, msg, closureOnError);
      },
      error: function(xhr, status, e) {            
          showException(controlInfo.id, status);
  
      }
  
  });
  </code></pre>
  
  <p>On the backend I have a java struts action to handle the xhr. I need to use the encoding ISO-8859-1 in the page to ensure the data (specially accented characters) are sent correctly in the synchronous submit.</p>
  
  <p>All's working like a charm in Firefox but when I have to handle an async post from IE 7 with accented characters I have a problem: I always receive invalid characters (utf-8 maybe?).
  EG I type in the form àààààààà and I get in my request this value: Ã Ã Ã Ã Ã Ã Ã Ã.
  Since the request charset's correctly set to ISO-8859-1 I can't understand why the server's still not parsing the form value correctly.</p>
  
  <p>This is a log sample with all the request headers and the error (the server's an old Bea Weblogic 8.1):</p>
