[issue18818] Empty PYTHONIOENCODING is not the same as nonexistent

[STINNER Victor]

STINNER Victor added the comment:

Patch looks good to me, but you have to update Doc/using/cmdline.rst,
at least to add a versionchanged section.

Tests would also be nice :-)

I really like the the "PYTHONIOENCODING=:surrogateescape" use case!
