    Re: encoding problem

    When you send the contentType header, make sure you declare a character set that is compatible with Arabic. I believe UTF-8 contains Arabic.

    Re: encoding problem

    I said, when you send the headers. Declaring them in the client-side documents isn't enough.

    First, you need to declare them in any server-side document you are using. For PHP...

    PHP Code:
    header('Content-Type: text/html; charset=utf-8'); 
    Second, You might need to declare the Content-type header in the AJAX when you send it.

    Code:
    obj.open('POST', url, true);
    obj.setRequestHeader('Content-type', 'application/x-www-form-urlencoded;charset=UTF-8');
    obj.setRequestHeader('Content-length', parameters.length);
    obj.setRequestHeader('Connection', 'close');
    obj.send(parameters);

    url=url+"&sid="+Math.random();
    soapRequestStr='<?xml version="1.0" encoding="utf-8"?>';
    xmlHttp.onreadystatechange=stateChanged;

    Re: encoding problem

    I have done much testing and so long as I supply the proper header in the PHP file, it works for me. Try the following attached zip file.

    arabic.html
    Code:
    <html>
    <body>
    
    <script type="text/javascript">
    var AJAX = {
      initialize: function(){
        var xmlHTTP;
        try{xmlHTTP = new XMLHttpRequest();}
        catch(e){
          try{xmlHTTP = new ActiveXObject("Msxml2.XMLHTTP");}
          catch(e){
            try{xmlHTTP = new ActiveXObject("Microsoft.XMLHTTP");}
            catch(e){
              alert("Your browser does not support AJAX!");
              return false;
            }
          }
        }
        return xmlHTTP;
      },
    
      get: function(url, func){
        var obj = this.initialize();
        obj.open('GET', url, true);
        obj.send(null);
        obj.onreadystatechange = function(){
          if(obj.readyState == 4){
            func(obj.responseText);
          }
        }
      }
    }
    
    function getUpdate(txt){
      document.getElementById('getReturn').innerHTML = txt;
    }
    </script>
    
    <input type="text" id="test" name="test" value="blah" onkeyup="AJAX.get('test.php?x=' + this.value, getUpdate)" />

    Re: encoding problem

    I tested my example on multiple machines, servers, and OSs. It works. So, that means that it is something on your end. Possibly the browser you are using. Have you tried using IE, Firefox, and Safari?

    Re: encoding problem

    Dear Sir,
    Have you checked with arabic characters as input? i.e. send س سص فخ to test.php file and get the output at arabic.html.
    i tested with IE,mozila . this is same problem i.e i got the error output as a ? ? ? for input text arabic characters.

    The problem is only with arabic characters,.
