Michael Youngstrom resolved JBSEAM-3148.

    Resolution: Won't Fix

Looks like the documentation already details useBodyEncodingForURI="true" my bad. :)

> I am having trouble transmitting multi-byte characters through page params.  The problem appears to be this:
> 1.  The servlet spec defaults URI decoding as ISO-8859-1.
> 2.  Calling request.setCharacterEncoding() changes this default for the body of the message (post params)
> 3.  In Tomcat calling request.setCharacterEncoding() does not change the encoding tomcat uses to decode the url.  In order to change the uri encoding the useBodyEncodingForURI=true must be set in tomcat configuration (http://tomcat.apache.org/tomcat-5.5-doc/config/http.html).
> 4. A seam redirect uses seam.core.Manager.encode() to encode request params which encodes the parameters using UTF-8.
> 5. So when a multi-byte character is communicated as a page param by default it gets encoded by Seam in UTF-8 and decoded by Tomcat using ISO-8859-1.
> How do we fix this?  Two options:
> 1. Change Manager.encode() to use ISO-8859-1 instead of UTF-8 by default.
> 2. Make everyone who uses tomcat set useBodyEncodingForURI=true in their configuration.
> I don't know if tomcat is the only container that doesn't by default URIDecode using the same content type as request.setCharacterEncoding().
> I'm leaning towards option #1.  Thoughts?
