Please address UTF-8 mode explicitly in open() or elsewhere. The locale
module is about the state of the lib C, not what Python enforces via
options in its own I/O layers.
As mentioned, both should ideally be synchronized, though, so
UTF-8 mode in Python should trigger setting a UTF-8 enc
gs :-) So this is unnecessary as well.

If it does work, getencoding() could just be a shim over
nl_langinfo(CODESET) on all platforms.

specific to Python's view on I/O (sys or io) or the file system (os).
Hopefully, in a few years, we can get rid of all this and standardize
on UTF-8 everywhere.

I had added locale.getdefaultlocale() to give applications a chance
to determine the locale setting defined by the process environment
*without* calling setlocale(LC_ALL, '') and causing problems
in other threads. I used the X11 database for locale encodings,
