You should keep things more simple:

- Python and the operation system/filesystem are in a client-server relationship and Python should validate all.
- It doesn't matter what you will finally decide to be the default encoding on various places - all will provide race-conditions with no exception.
- The easiest way to fix this is to give the developer the ability to make a decision (like sys.use_strict_encoding(), sys.setfilesystemencoding(), sys.setdefaultencoding() etc.).
* For example giving the developer control is especially needed if he wants to handle multiple different filesystems.

sworddragon@ubuntu:~$ LANG=C
sworddragon@ubuntu:~$ ä
bash: $'\303\244': command not found

- The terminal doesn't pseudo-crash with an exception because it doesn't matter about encodings.
- It allows to change the encoding at runtime.

Compare C: It wouldn't matter like the terminal. For example fopen will simply return NULL if it can't open the file 'ä' because the filesystem is endoded with ISO-8859-1 and we wanted to open the utf-8 counterpart.

For example I'm using this for testcases to set the language uncomplicated to english.
