To some extent it depends on the file system, and to some extent it's
down to the kernel, but I don't know of any Unix/FS combination that
permits 0 (null) bytes in file names.  I can't see how it could work.

And almost all file systems will prohibit the use of / in a file name,
though I've heard you can trick NFS into taking it.

Some file systems (depending on mount options) can have complex rules
such as rejecting any name with an invalid UTF-8 sequence.
