GWT: encode url with encoding scheme
Is it possible to encode a url-parameter using a specific encoding scheme in GWT?
URLEncoder.encode(string, "ISO-8859-1");

works for me in standard java but isn't available in GWT.
URL.encode(string);

encodes in GWT with "UTF-8".
An encoding can not be specified

I think it is not possible. Take a look here
