Correct me if I’m wrong, but I think in Python 3.7 on Windows 10, the filesystem encoding is already UTF-8, and the stdio console files are UTF-8 (but under the covers actually wrap the native UTF-16 console APIs instead of using msvcrt stdio), so the only issue is the locale encoding, right? Also, PYTHONUTF8 is only supported on Unix, so presumably it’s ignored if you set it on Windows, right? If so, you need to also add support for it, not just set it in the installer. And presumably you also want to add the equivalent command-line argument to Windows also One last thing: On Linux, you often use the locale coercion feature instead of the assume-UTF-8 feature. (For example, if you’re running a subprocess and want to ensure its stdout is UTF-8…) Is there an equivalent issue for Windows, or a very different but equally important one that needs to be solved differently, or is there just nothing relevant here? > * Windows 10 (1903) adds per-process option to change active code page > to UTF-8 and call the system code page "legacy". If you do that, won’t Python 3.7 already use UTF-8 for the locale, because the active code page is what it sets the startup value to match? > But it is difficult to change the default text encoding of Python > for backward compatibility.

If you’ve used the Windows 10 feature you mentioned above, won’t this just select the same UTF-8 you’re already using? Or are you suggesting that Python’s mbcs codec should also change to (on Windows when UTF8 is enabled) use “legacy” if it exists and only otherwise use actual “mbcs”? Or that nobody should use this Windows feature on Python 3.8+? _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/SSB7C5QMG5BRIIYFUNFDCOGAFDG7MOID/ Code of Conduct: http://python.org/psf/codeofconduct/
