CS_PATH is hardcoded to "/bin:/usr/bin" in the GNU libc for UNIX. Do you know 
another key for which the value can be controled by the user (or the system 
administrator)?

CS_PATH is just an example, there are other keys. I'm not sure that all values 
are encoded to the filesystem encodings, it might be another encoding?

Well, if we really doesn't know the encoding, a solution is to use a bytes API 
(which may avoid the question of the usage of the PEP 383).
