I don't recommend repr(obj).encode('unicode_escape'), because
backslash characters in the string will be escaped again by the codec.
>>> print(repr("\\"))
'\\'
>>> print(str(repr("\\").encode("unicode-escape"), "ASCII"))
'\\\\'
'ASCII' codec with 'backslashreplace' error handler works better.
>>> print(str(repr("\\").encode("ASCII", "backslashreplace"), "ASCII"))
'\\'
Looks complicated to get same result as Python 2.x. I originally
proposed to allow print(repr('\\'), encoding="ASCII",
errors="backslashreplace") to get same result, but this is hard to
implement.
If requirement for ASCII-repr is popular enough, we can provide a
built-in function like this:
def repr_ascii(obj):
return str(repr(obj).encode("ASCII", "backslashreplace"), "ASCII")
2to3 can use repr_ascii() for better compatibility.
Is new built-in function desirable, or just document is good enough?
