Excellent post. This is not an issue of Prototype library - the encoding attribute of Ajax.Request has nothing to do with the way encodeURIComponent() works, which may be surprising to some.

The server-side iconv solution seems indeed the simplest.

When you use iconv don't forget to add headers
'Content-type: text/html; charset=windows-1256'
to your controller!

it saved my life :)
congratulations
very good.

Thank you very much! Your advice and iconv did the job.

excelent post! thanks!

header('Content-type: text/html; charset=iso-8859-1');
//+
$texto = iconv("UTF-8", "iso-8859-1", $_POST['texto']);

that saved my life

Thank you for your advice.

I tried many times to solve this problem, but it's not working. Still print "garbage data".

I used windows-1256, and I used this :

thank you

I am using classic ASP and my pages and db are in windows-1251 encoding. Now I am trying to use AJAX and facing this problem. What am I suppose to do when there is no ICONV equivalent in ASP 3.0. I have been looking all over Internet for somebody who has already created such function without luck.

This is the method I call onboady load:

function getInitialTree(){
tree=new dhtmlXTreeObject('treeBox',"100%","100%",0);
tree.setImagePath("../../images/");
tree.enableIEImageFix(true);
tree.attachEvent("onClick",onNodeClick);
url = "/treecontroller?Action=GetDhtmlxTreeXML";
tree.setXMLAutoLoading(url);
tree.loadXML(url+"&framework.actionContext=20");
}

It gets a perfectly valid XML file encoded in iso-8889-1 (but could be anything else);

The problem I get is that the tree doesn't show on screen, instead I get a msg saying that the the XML is incorrect and when I hit "Generate Report" it shows me my XML file with the right encoding in its header, but the special french characters I use get all scrumbled. How is this possible and how can I solve it? I get the impression that whatever the encoding indicated in the header, the tree translates it into utf-8.

Btw, I know the file is ok, because I am able to see it in the browser when consulting the same url (IE). If I change the encoding to utf-8 in the XML file on the other hand, IE throws an exception.

Thanks.

Georgi, try to put the following on the ASP page that you call with a ajax request :

Response.CodePage = 65001
Response.CharSet = "utf-8"

this did the trick for me

This article is more than GREAT, you saved my time ... I was going to use the charset convert class.
For those who may interest in using a class to do this:
