Description: Reference implementation for PEP 538, which is in turn a partial fix for bpo-28180. This updates the CPython CLI to attempt to set LC_CTYPE to a suitable UTF-8 based locale before loading the runtime when it detects that it is running in the C locale. It also updates the CPython runtime to emit a compatibility warning on stderr when running in the C locale. Remaining work: Fix the Windows compatibility issue reported by Appveyor What's New entry Add a note in the What's New entry regarding the current locale coercion warning that indicates we're actively seeking feedback on it during the 3.7 pre-release cycle. Our experience with the Fedora 26 backport so far has been that the warning is useful in spotting places where we should probably change the configured locale to C.UTF-8 (e.g. in RPM build environments), but I'm still starting to wonder if it might be better for us to disable it before the F26 final release.
