Yes, Python3 decodes environment variables using sys.getfilesystemencoding()+surrogateescape. And since my last fix on os.execve(), subprocess (and os.execv(p)e) uses also surrogateescape to encode environment variables.
And yes again, I also patched os.getenv() to decode bytes name to unicode using sys.getfilesystemencoding()+surrogateescape.

*fs*encode() and *fs*decode() is a reference to the encoding: sys.get*filesystem*encoding().
