I agree. AFAIK, in HTTP 1.1 this isn't fixed either. There is no reason
the Servlet API should be broken just because HTTP is broken. If a
ServletRequest.setCharacterEncoding method was added to the Servlet API, it
could be called from the servlet prior to any calls to request.getParameter
which would allow the built in parameter support to work for any character
encoding.

Thanks, this is very helpful.
