I'm not sure it does. EOF is a negative integer. Usually, that would mean
that EOF is outside the range of unsigned char. However, if unsigned char
is the same width as int, then the situation is reversed; many unsigned char
values get converted when used as ints. In this case, it is not possible
to tell whether EOF is a magic sentinel value or not. However, it is possible
to check, upon receiving a value comparing equal to EOF, whether feof() or
ferror() is true.
I can't see anything in the standard which actually requires int to be larger
