New submission from Armin Rigo <armin.rigo at gmail.com>:
The user can raise an exception with a unicode error message. But the
interpreter displays it (after a traceback) in an very ascii-oriented way.
The behavior is arguably very bogus on CPython: it doesn't print the unicode
message at all if it's not purely ascii.
The traceback.py module (and so PyPy) are slightly better: they convert and
print the message with `.encode("ascii", "backslashreplace")`. While this might
be enough for western languages, it is not really useful in languages like
Chinese: you get "Exception: \u1234\u1235\u5212".
We should decide if this is worth improving in traceback.py, and if so, do it.
(Fwiw CPython seems to believe that keeping the error messages perfectly
unreadable is a good way to push forward for Python 3, so it's unlikely to get
