Per David Wheeler's excellent "Fixing Linux/Unix/POSIX Filenames"[1]:

 Traditionally, Unix/Linux/POSIX filenames can be almost any sequence
 of bytes, and their meaning is unassigned. The only real rules are that
 “/” is always the directory separator, and that filenames can’t contain
 byte 0 (because this is the terminator).
