On Posix systems, it's wrong to even treat filenames as Unicode strings;
according to the standard, they are null-terminated byte strings that
can't include 0x2F. From that perspective, filenames are a unique type
that musn't be mangled by any Unicode operation, including conversion
between UTF-8 and UTF-16. Of course, users expect to see them as
strings; one solution for this that also works for the normalization
case is to keep a table of filenames and the Unicode version thereof,
which may be normalized.
