Sorry. I probably wasn't clear enough in my message. I understand
the issue, and I'm not discussing source encoding at all. The
only problem I'd like to solve is that of output streams not
being able to have unicode strings written.

I don't see that as a good solution, since every Python software
that is internationalizaed will have do figure out this wrapping,
introducing extra overhead unnecessarily.

That's what I think as well. I just would expect that Python was
kind enough to allow me to tell which output encoding I want,
instead of wrapping the sys.stdout object with a non-native-file.
IOW, being widely necessary, handling internationalization without
wrapping sys.stdout everytime seems like a good step for a language

Thanks for the suggestion!
