[New-bugs-announce] [issue4599] Strings undisplayable with repr

[Michael Foord]

New submission from Michael Foord <michael at voidspace.org.uk>:

In Python 3 strings with non-ascii characters are undisplayable (even
with repr) in the default interactive interpreter on Windows and Mac.
Shouldn't the repr use escapes as with previous versions of Python?
