Take out the ;charset=UTF-8 part of the content type meta header, and any UTF-8 content type header you may be sending at the server. If you are using an <?xml etc ?> directive, take out the charset (or is it encoding?) attribute.

Your page reports being encoded as UTF-16LE... But if you try to serve it as that when it's not encoded as that, then it wont help you much. Is that page the result of server side software ( i.e. PHP etc ) that might be adding anything to the page's HTTP header?

Can you post the original page source? In view source it comes up with those foreign characters also.
