do you still have that problem in 1.1?
It should be fixed there. Because we now use for rendering and form
input the same encoding that can be set in
ApplicatonSettings the ResponseRequestEncoding
The only problem that can happen now is that the user overrides in the
browser the encoding..
But that can't be fixed because the browser doesn't send the encoding
that it uses in a header or something like that.

Hi,
There is known problem with form parameters encoding and servlets. When you
have utf-8 HTML page with forms, you get back the parameters in utf-8, but
the servlet doesn't know, that the page was rendered in utf-8 and interprets
the parameters in different encoding (don't know exactly which one). You can
fix the problem with servlet filter show bellow (code is from Tomcat I
suppose). I think that Wicket should include the filter in its distribution.
What do you think?
