title: php get data on IE (Greek char) does not work
body: <p>I have two pages and I use AJAX in order to do some tasks without refreshing the page.
  The problem is when I use Internet Explorer, I got the value as '?'. What I try to do is to have a catalog and when a user clicks on a character, the other page is performing SQL tasks and the first page presents the results. </p>
  
  <p>First page:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;meta http-equiv="X-UA-Compatible" content="IE=9"/&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
  &lt;script&gt;
  function loadXMLDoc(myLink)
  {
  alert ("OK");
  var xmlhttp;
  alert (myLink);
  if (window.XMLHttpRequest)
    {
    xmlhttp=new XMLHttpRequest();
    }    
  xmlhttp.onreadystatechange=function()
    {
    if (xmlhttp.readyState==4)
      {
      document.getElementById("information").innerHTML=xmlhttp.responseText;
      }
    }      
  xmlhttp.open("GET","select.php?data=" + myLink,true);
  xmlhttp.send();
  }
  &lt;/script&gt;    
  &lt;/head&gt;
  &lt;body&gt;
  &lt;center&gt;
  &lt;font size = "4"&gt;     
   &lt;a href = "#" onClick = "loadXMLDoc('Ι'); return false;"&gt;Ι &lt;/a&gt;      
   &lt;/font&gt;
  &lt;/center&gt;    
  &lt;div id = "information"&gt;
  &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The second page:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;meta http-equiv="X-UA-Compatible" content="IE=9"/&gt;    
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;?php
  //var_dump($_GET);
  //exit();
  session_start();
  $find = $_GET["data"];
  $find = iconv("utf8", "utf8", $find);
  echo "New find = " . $find;
  $find = iconv("utf8", "utf8", "Ι"); //Greek character
  echo "&lt;br/&gt;Newest find = " . $find;
  ?&gt;
  </code></pre>
  
  <p>The first 'echo' will print a questionmark ('?') while the second one will print the proper character. That problem appears only on Internet Explorer, it works on any other.
  If I use the 'var_dump', I get:</p>
  
  <blockquote>
    <p>Internet Explorer: array(1) { ["data"]=> string(1) "?" }</p>
    
    <p>Chrome and Mozilla: array(1) { ["data"]=> string(2) "Ι" }</p>
  </blockquote>
  
  <p>No problem at all with AJAX.</p>
  
  <p>Any help please?</p>
