How to encode/decode utf8 in ajax requests?

My page is encoded in iso-8859-1, but how can you easily encode the data to utf8 when sending and decode again when reveicing the response?

function Ajax(){
    var _this = this;

    this.url = null;
    this.data = null;
    this.success = null;

    this.global = true;
    this.timeout = JSON_TIMEOUT;
    this.cache = false;
    this.dataType = 'json';
    this.type = 'post';

    this.send = function(){
        var jqxhr = $.ajax({
                url : this.url,
                data : this.data,
                timeout : this.timeout,
                cache : this.cache,
                dataType : this.dataType,
                type : this.type,
                global : this.global
                }
            )
            .success(this.success)
            .error(function(){
                // something
            })
            .complete(function(){

            });
    };
}

You don’t need to do anything. jQuery’s ajax() function will always transmit the data in UTF-8.

It doesn’t matter what your page is encoded in because Javascript always uses Unicode internally and properly translates your iso-8859-1 page.
