I think the proposal to introduce two standard properties is good and is
consistent with the recently introduced native.encoding. I'm not 100% sure that
the sentence "The property may be set on the command line ..." is appropriate
for the spec of standard properties. We got away with that for file.encoding in
implNote but that isn't spec. I think we may have to replace this with
something that says that the Java runtime can be started with the system
property set to "UTF-8", starting it with the property set to another value
clears to undefined behavior.
