ken and i wrote a paper about how and why it is more than
'hardly different' (http://plan9.bell-labs.com/sys/doc/utf.pdf).
there are two important differences. first is that (old) ANSI C
did not provide any formatted i/o for wchar_t, rendering them
essentially useless. second, more subtle but probably more
central, the way plan 9 handles encoding errors with runetochar
and chartorune, by introducing the 'error rune' 0x80, is vastly
more convenient and effective than the error return values set
by mbtowchar stuff.
