As I said, the functions are only defined for EOF and unsigned char. All
other values are undefined (and may even crash on some systems...).

In fact it is a good practice to have all strings of type unsigned char.
It is very easy to get confused when someone uses national (8 bit)
characters otherwise.

It is a pity that char by default is unsigned when almost no one thinks
of characters as being signed. Some compilers (including gcc) has a flag
for turning char into unsigned, but this is compiler specific and should
not be relied on in a portable application.
