And eventually I'll listen, I promise Alex. :-)

While I'm leery of hastily choosing utf8 as our core string
representation (I feel that this issue *does* involve internal
representation for that very reason, though admittedly not in the same
sense) I agree 100% that Unicode support should be core. And on that
note I'll stop muddying the waters and give my +1 to copying utf8 into
the core and adding a suite of byte- functions.
For what it's worth, I also think that GMP should be in the core, and
that no one, nowhere should be allowed to publish an egg with a
toplevel procedure named (format) in it. Mysterious toplevel
interactions between indirect dependents are the bane of good
software.
