At the moment, PGE (the part that implements the rule engine) is deferring such questions to Parrot, and otherwise assuming Unicode. Plus, S02 explicitly indicates that Perl is written in Unicode and has consistent Unicode semantics, so I think that's what we should go with. It's certainly the way the compiler will go, at least initially. Pm
