how to change the encoding of a JSON-file in javascript

Question

I've used flash CS6 to export an animation to a spritesheet. This gives me 2 files: a png and a json file.

this is a simplified version of the json:

{"frames": 
{
    "movieclip 10000":
    {
        "frame": {"x":676,"y":0,"w":164,"h":280},
        "rotated": false,
        "trimmed": false,
        "spriteSourceSize": {"x":0,"y":0,"w":164,"h":280},
        "sourceSize": {"w":164,"h":280}
    },
    …
    "movieclip 10004":
    {
        "frame": {"x":671,"y":280,"w":164,"h":280},
        "rotated": false,
        "trimmed": false,
        "spriteSourceSize": {"x":0,"y":0,"w":164,"h":280},
        "sourceSize": {"w":164,"h":280}
    }
},
"meta": {
    "app": "Adobe Flash CS6",
    "version": "12.0.2.529",
    "image": "boom1 8B4 def.png",
    "format": "RGBA8888",
    "size": {"w":1024,"h":1000},
    "scale": "1"
}

Nothing special here. But the file is encoded in (according to textwrangler) UTF-16 Little Endian. This doesn't give any problems in Chrome, but when parsing the json in FF I get a "parsererror".

When I change the encoding of the file, it works without any problem in firefox.

So here is my question : (How) can I change the encoding using javascript?

this snippet is how I load my json:

$.ajax({
    type: "POST",
    url: this.json,
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(json) {
        that.jsonLoadHandler(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        that.errorHandler(xhr, textStatus);
    }
});

Thank you for your time.

Instead of contentType: "application/json; charset=utf-8" use only contentType: "application/json;" this may resolve your problem.
