> From the C99 spec:
> {quote}
> The header <ctype.h> declares several functions useful for classifying and
> mapping characters. In all cases the argument is an int, the value of which
> shall be representable as an unsigned char or shall equal the value of the
> macro EOF. If the argument has any other value, the behavior is undefined.
> The behavior of these functions is affected by the current locale.
> {quote}
> There are many cases where we pass unchecked {{char}} values which might be
> negative.
