The string formatting code has a test to switch to Unicode when %s
sees a Unicode argument. Unfortunately this test was also executed for %r, because %s and %r share almost all of their code. This meant that, if u is a unicode object while repr(u) is an 8-bit string containing ASCII characters, '%r' % u is a *unicode* string containing only ASCII characters! Fixed by executing the test only for %s. Also fixed an error message -- %s argument has non-string str() doesn't make sense for %r, so the error message now differentiates between %s and %r.
