I was thinking we would end up using the console API for input but stick with the standard handles for output, mostly to minimize the amount of magic switching we have to do. But since we can just switch the entire stream object in __std*__ once at startup if nothing is redirected it probably isn't that much of a simplification.

At this point what codepage does Python see? What codepage does > process X see? (Note that they are both sharing the same console). The input and output codepages are global data in conhost.exe. They aren't tracked for each attached process (unlike input history and aliases). That's how chcp.com works in the first place. Otherwise its calls to SetConsoleCP and SetConsoleOutputCP would be pointless. But IMHO all talk of using codepage 65001 is a waste of time. I think the trailing garbage output with this codepage in Windows 7 is unacceptable. And getting EOF for non-ASCII input is a show stopper. The problem occurs in conhost. All you get is the EOF result from ReadFile/ReadConsoleA, so it can't be worked around. This kills the REPL and raises EOFError for input(). ISTM the only people who think codepage 65001 actually works are those using Windows 8+ who occasionally need to print non-OEM text and never enter (or paste) anything but ASCII text. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
