Regarding AJAX charset

Hi ,
I have this problem for long time and i am still hunting the right answer or method to solve this.
NOTE : **** = charset other than UTF-8

Ajax request will have a Charset UTF-8 and
Response Charset is **** (not UTF-8).

Now i want to change the Request charset to **** so ,both the request and response will have the same charset. (I dont want UTF-8 ,because my php content holds **** charset).

I have tried to Meta header ,header and even hard coded the ajax request header in the ajax call.

But it is working in its own way.
and i try to add this **** in accept charset and it also failed.

Due to this problem i am getting error in IE and my entire application collapse .

I hope alot of people have this problem ,but i dont know who will have answer to this issue .

Awaiting for any positive response .

 

Add this to your ajax call replacing with the proper charset :

$.ajax({
        data: parameters,
        type: "POST",
        url: ajax_url,
        timeout: 20000,
        contentType: "application/x-www-form-urlencoded;charset=ISO-8859-15", <-----
        dataType: 'json',
        success: callback
});

Hi ,
i have tried that too ,It didn't reflect that charset ,it still send as utf-8 only.
