[jQuery] Foreign charachters in .post()

[jQuery] Foreign charachters in .post()

Hi,
Got a bit of a weird one here :/
The following code works fine:
     jQuery.post
"/cgi-bin/review.cgi", {
     Review_Rating: the_rating,
            ID: theID,
            add_this_review: 1,
            Review_Contents: contents,
            Review_Subject: subject,
            Review_ByLine: byline,
            Review_GuestName: guestname,
            Review_GuestEmail: guestemail,
            add_review: 1,
            SecurityImage: SecurityImage,
            SessionID: SessionID
     }, function
response
{
     jQuery
'#ajax_rate_indicator'
.fadeOut
;
     setTimeout
"finishAjaxReview
'the_rating_box', '"
escape
response
"'
", 400
;
     }
;
...*appart* from the fact stuff like:
ö =
ä =
ü =
..gets converted to:
ö =
ä =
ü =
I did a little bit of research, and found something about adding this
but this seems to really be for a different jQuery function - which
is probably why its not working
;
            contentType: "application/x-www-form-
urlencoded;charset=ISO-8859-15",
Can anyone suggest how I could fix this issue with foreign
charachters?
TIA
Andy
