Sorry for replying so late, I am currently catching up with my emails ...
I am also very interested in maintainign an internationalized site in 
OpenCMS and I am willing to help. The charsets I usualy use are
ISO-8859-2 and UTF-8.

When you receive a submitted form, the parameters are in the same
encoding as was the page with the form. You have to call
request.setCharaterEncoding() to convert them so that
request.getParameter() will return correct Java characters.
This call is best to place into a class extending javax.servlet.Filter
and configured as filter for all requests in web.xml

One thing to be aware of is that in TomCat 5 parameters trasmitted
in URL (i.e. GET parameters or in the case of POST additional parameters
from the URL) are *NOT* affected by request.setCharacterEncoding()
unless you set a flag on the TomCat Coyote connector in server.xml.
I had a disscussion about this on the TomCat list, but the TomCat
authors decided that it is the right thing to do and internationalized
data should not be transmitted in URL. The discussion was quite
heated and the only result was the flag for backward compatibility.

Best regards,

Martin
