I just fixed the mojibake issue in Python 3.8 by disabling C locale coercion and UTF-8 Mode by default. I'm not sure if nor how Python 3.7 should be fixed in a minor 3.7.x release.
That sounds like a potential regression. Those two features were added *and turned on by default* (which really means "if you detect LC_TYPE=C, coerce") to relieve previously existing mojibake/ UnicodeError issues due to ASCII-only environments that are difficult to configure (such as containers). Turning them on by default was the controversial part -- it was known that on or off, some environments would have problems, and that's why they needed PEPs. Do those issues return now? If so, where is the PEP rationale for defaulting to "on" faulty?
