[issue38667] PYTHONCOERCECLOCALE=0 ignored

[Christoph Reiter]

New submission from Christoph Reiter <reiter.christoph at gmail.com>:

Python 3.7.5rc1 and 3.8.0 on Ubuntu 19.10

$ LC_CTYPE=C PYTHONCOERCECLOCALE=warn python3 -c "import sys; print(sys.getfilesystemencoding())"
Python detected LC_CTYPE=C: LC_CTYPE coerced to C.UTF-8 (set another locale or PYTHONCOERCECLOCALE=0 to disable this locale coercion behavior).
utf-8

$ LC_CTYPE=C PYTHONCOERCECLOCALE=0 python3 -c "import sys; print(sys.getfilesystemencoding())"   
utf-8

The warning states that passing PYTHONCOERCECLOCALE=0 disables the coercion, but it doesn't change anything in 3.7 and 3.8.

What am I missing?
