This is just impossible due to compatibility reasons.
Nearly all existing applications assume that the encoding of pathnames
is same with the codeset of current locale.
Thus, if UTF-8 was only allowed for system call interface, all people
except who only use US-ASCII got catastrophic results.
The way also conflicts with the locale concept that applications only
have to use single codeset (i.e. the codeset of current locale).
