Looking at the source code, there appears to be a mismatch between
MSVCRT_fgetwc() and MSVCRT_ungetwc(): the latter ignores all the smartness of
the former, and just feeds all the bytes of its argument to MSVCRT_ungetc() one
by one.

However, in case of a file without BOM, the file position after the first
fgetwc() is rightfully 1; as a result, only one of the two MSVCRT_ungetc()
succeeds.
