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

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

In Python 3 ascii() uses the backslashreplace error handler.

>>> class T:
...     def __repr__(self):
...         return '\u20ac\udcff'
... 
>>> print(ascii(T()))
\u20ac\udcff

I think using the backslashreplace error handler in repr() in Python 2.7 is good solution. Here is a patch.
