Hello Chris,
1. If the filter does not influence the decoding of the GET parameters
why is it called on GET requests?
2. How about http : PUT, HEAD, etc?
3. I did what this page says:
http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q8
What if I want to build a fully UTF-8 application that will be posted on a web
hosting provider where I have no access to server.xml (because this is a common
file)?
4. I didn't sniff the wire - I only had a look at the URL I send with
the javascript alert function.
5. "Utf8encode" converts Unicode strings to strings of bytes in UTF-8
encoding
(see here: http://www.webtoolkit.info/javascript-utf8.html).
6. "escape" (a standard script function) converts characters not
acceptable for http (like slashes)
to the %XX notation.
7. Combined escape(Utf8encode("larevoluție"))="larevolu%C8%9Bie"
8. POST is not really an acceptable solution because I don't know in
advance what the keys of the request will be ("Name" in
the example) neither how many they are & POST requires using a html <form>.
(what I do is build an
URL in javascript/emacscript from a structured object returned by
showModalDialog then alert(scriptBuiltUrl);
window.location=scriptBuiltUrl;
). Thank you for your help.
Mircea

Of course.

The filter cannot influence the way that GET parameters are decoded. The
only way to change that is to set URIEncoding="UTF-8" on your
<Connector> in server.xml.
Your best bet is to transfer all non-US-ASCII data in request /bodies/
by using HTTP POST.
If HTTP POST is not acceptable, please let us know why and perhaps we
can suggest some alternatives.
This looks a bit weird to me:

What does the Utf8encode function do? What does the escape function do?
Have you tried snooping the HTTP conversation using a browser plug-in
and/or a line sniffer like Wireshark? What does the data doing over the
TCP/IP connection look like?
