i use alot ajax and always use only utf8 and never had a problem , i'm mostly on chrome and safari ios

maybe try changing ur ajax script by removing all the headers.and using the new FormData (should work on most modern browsers) ... sure not on all.

document.forms[0] means it takes all the fields from first form in your page. else give it an id and call document.getElementById('myform') i also don't use anymore readyState... onload

to return the response in postresponsefunction u write this.response

var fd=new FormData(document.forms[0]),
c=new XMLHttpRequest();
c.open('POST',strURL);
c.onload=postresponsefunction;
c.send(fd);

here is a complet working php script with post & ajax file is named 'test.php'

<?php
if($_REQUEST){
print_r($_REQUEST);
}else{
?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>postajax</title>
<script>
var 
rf=function(){
 document.getElementsByTagName('div')[0].innerText=this.response;
},
sf=function(e){
 e.preventDefault();e.stopPropagation();
 var fd=new FormData(document.getElementsByTagName('form')[0]),
 c=new XMLHttpRequest();
 c.open('POST','test.php');
 c.onload=rf;
 c.send(fd);
};
window.onload=function(){
 document.getElementsByTagName('form')[0].onsubmit=sf;
}
</script>
</head>
<body>
<form>
<input type="text" name="mytext"><input type="submit" value="submit">
</form><div></div>
</body>
</html>
<?php
}
?>

if (!window.XMLHttpRequest) {
  window.XMLHttpRequest = function() {
    return new ActiveXObject(”Microsoft.XMLHTTP”);
  };
}
