Setting errors to surrogateescape or encoding to Latin-1 causes Python 3 to behave the exact same way as Python 2: it's doing the "wrong" thing and may result in mojibake, but at least it isn't screwing up anything new so long as the stuff you add to the file is in ASCII. The only way to make Python 3 slightly more like Python 2 would be to set errors="surrogateescape" by default instead of asking the programmer to know to use it. I think that would be going too far, but it could be done. I think it would be simpler though to just publicize errors="surrogateescape" more.

So something like this:
import functools, builtins
open = builtins.open = functools.partial(open, encoding="ascii",
