code that uses repr() on unicode strings.

it might be a good idea to add a helper function that does something like:

    preferred_encoding = locale.get...

    def nicerepr(value):
        if isinstance(value, unicode):
            return repr(value.encode(preferred_encoding, "replace"))
        if isinstance(value, list):
            return repr(map(nicerepr, value))
        return repr(value)

and use this instead of repr() and %r, where applicable.
