title: JQuery Ajax not returnig utf-8 characters
body: <p>i have ajax function that looks like this:</p>
  
  <pre><code>jQuery.ajax({
      type: 'POST',
      data: {
          action: 'get_data',
          article_id: some_var
      },
      url: 'http://www.example/test.php',
      success: function(msg) {
      jQuery('#some_div').html(msg);
      }
  });
  </code></pre>
  
  <p>In test.php i have mysql query that gets row from base, with id that is equal to article_id. It works good. BUT i have some serbian language characters in database, and when ajax returns that characters, they look like this: "Ž" is "�", and "Š" is "?".
  Data is corectly stored in mysql (utf8 connections, colations and all other stufs), html page encoding is utf8... I am missing something, i dont know what...</p>
