Hmm, is it really bytes?  Or (multibyte) characters?

Suppose MB_LEN_MAX == 2 and that '@' is a two-byte character whose bytes are
{0x84, 0x30}.  If I call scanf("@") and the input stream contains 0x84 0x31,
does it push back one byte or two?  Would it make any difference if I wrote it
as scanf("\x84\x30")?
