The 0xfd is an invalid multibyte character, so it can't be converted to
a wide character. mbsnrtowcs returns 0, which is kind of a dodgy error
(mbrlen returns -1 for the same character, for instance), but the code
doesn't handle that case.
The question is how to best handle it: punt immediately, or just treat it
as a single-byte character and move on.
