[issue5876] __repr__ returning unicode doesn't work when called implicitly

[Armin Rigo]

Armin Rigo <arigo at users.sourceforge.net> added the comment:

A __repr__() that returns unicode can, in CPython 2.7 be used in  "%s" % x  or in  u"%s" % x  --- both expressions then return a unicode without doing any encoding --- but it cannot be used anywhere else, e.g. in  "%r" % x  or in  repr(x).  See also the PyPy issue https://bugs.pypy.org/issue857 .
