No, you need to use int. The EOF value is deliberately outside the
range of character values so that EOF is not a valid character!
EOF is a valid character, 'ÿ', in the Latin-1 encoding on x86 and
various other architectures. On those architectures, EOF and 'ÿ' have
the same type and value as far as the C language is concerned. (In C++,
character literals have type char, so the types are different.)
