What do you expect to gain from that? Tomcat itself doesn't require it, and the webapps are expected to manage their own encoding.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
