Try compiling and running this in your production environment to see
what your defaultCharset is set to. As far as I can tell, there is NO
way to modify it after the JVM has started up.
import java.nio.charset.Charset;
public class charset {
public static void main(String[] args) {
System.out.println(Charset.defaultCharset().displayName());
}
}

Have you guys tried just using "-Dfile.encoding=UTF-8" when you run
the jvm which will run your app server (include it in JAVA_OPTS if you
run tomcat). That causes java to use UTF-8 as the charset for all
incoming and outgoing content by default. Otherwise, you have to
explicitly set the charset for every Reader and Writer you use, which
is impossible to do without re-writing large chunks of Tapestry
itself. I haven't had any issues with non-ascii characters in either
direction since I added that to my JAVA_OPTS and I had plenty of
problems before because the default charset in java on OS X was
MacRoman rather than UTF-8.
