AJAX explicitly set the encoding when sending out the post request

I am trying to send request using ajax with some japanese text.
As any of you know XMLHttpRequest is send with utf-8.

I was hoping there is a way to send with different encoding like

var parameters = "metadata=" +
encodeURI(document.getElementById("metadata").value);

http_request.onreadystatechange = metadataUpdate;
http_request.open( 'POST', "/servlet/SendJapText", true );
http_request.setRequestHeader( "Content-type",
"application/x-www-form-urlencoded;charset=Shift-JIS" );
http_request.send( parameters );

Thanks in advance.

var parameters = "metadata=" +
encodeURI(document.getElementById("metadata").value);

I would suggest to use encodeURIComponent and not encodeURI (as the
value to be encoded could e.g. contain '=' or '&' meaning with encodeURI
you would get with value 'Kibo&Xibo'
metadata=Kibo&Xibo
while with encodeURIComponent you get
metadata=Kibo%26Xibo
).
http_request.onreadystatechange = metadataUpdate;
http_request.open( 'POST', "/servlet/SendJapText", true );
http_request.setRequestHeader( "Content-type",
"application/x-www-form-urlencoded;charset=Shift-JIS" );
http_request.send( parameters );

If you set the Content-Type request header it is up to your code to
ensure the argument you pass to the send method is properly encoded.
Thus if you want charset=Shift-JIS then you can't use encodeURI
respectively encodeURIComponent as those do not use/support Shift-JIS as
the charset, rather UTF-8.
