To put more emphasis on this point: as things stand, you won't be able
to avoid having paths with illegal UTF-8.

Consider mounting a file system with UTF-8 file names over one
containing Latin-1 file names. Then even if both are consistent
in themselves (a far stretch, because there might be multiple apps
under multiple locales creating and naming files), the combined
path might be bad UTF-8

As long as the OS keeps out of this business I guess the application
will need a "layer" from which to look at paths (and env variables
and argv and all that) as mere byte sequences, before any interpretation
takes place.

This is so Microsoft: the file name character set in the file system
is Unicode... except when it isn't :-)
