I will look into this one.

Yes, my filter looked like a twin, with the exception, that I called
super.setCharacterEncoding(defaultEncoding) instead of manipulating the
content-type directly (and of course that defaultEncoding is different to
super.getCharacterEncoding() which would yield iso-8859-1). 
I could extend that filter to my needs. Should I file a enhancement
request for that?

I tried to let apache httpd now that in location /webapp the default
charset was different from iso-8859-1. But mod_jk ignored my pledges :(
Even so I think DefaultServlet should be able to set a charset if
configured to.
