Here's my idea.

repr() cannot convert 'unprintable characters', since repr() doesn't know
which characters are printable or not.

So, repr() should convert only non-printable "ASCII" characters and
special "ASCII" characters such as '\n". Other non-ASCII characters are
converted by output file. Output files can convert non-printable
characters to \uXXXX. Such conversions could be implemented by
backslashreplace error handler.

I wrote a quick patch. Please take a look at http://bugs.python.org/issue2630 .
