The PEP 538 only impacts platforms which provide the C.UTF-8 locale or a variant: only a few recent Linux distribution. I know Fedora, maybe a few other have it? FreeBSD and macOS are completely ignored by the PEP 538. The PEP 540 uses the UTF-8 encoding for the POSIX locale on *all* platforms. Moreover, the PEP 538 only concerns the POSIX locale (locale "C"), whereas the PEP 540 is usable with any locale. For example, using the "fr_FR.iso88591" locale, the encoding is Latin1. But if you enable the UTF-8 mode with this locale, Python will use UTF-8. The other difference is that the PEP 538 is implemented with setlocale(LC_CTYPE, "C.UTF-8"), whereas the PEP 540 is implemented in Python internals and ignores the locale. The PEP 540 scope is limited to Python, non-Python running in the same process is not aware of the "Python UTF-8 mode".
