Personally, I'm almost always in favor of compatibility with the JDK and
in this case there is no doubt in my mind that we should use UTF-8 by
default. I recognize that the system property is only a hack that solves
a limited number of scenarios, but it's better than nothing.

It is a violation of the Sun license included with the API specification
-- you could argue about whether the license is valid or not, but that's
not the point, and it would preclude us (or any JVM based on GNU
Classpath) from ever passing the TCK.
