do you mean to expect the "c == obuf[i]" test always true?
you should read the same byte sequences but wchar_t values corresponding
to the byte sequence is locale dependent.
while obuf is wchar_t for big5 locale (right?), what getwc returns
is wchar_t for another locale. comparing them with "==" doesn't make
(i'm not sure about the intention of the mixed use of getwc and getc
in the program, though.)
