32// The behavior of many of the functions in the <ctype.h> header is dependent
33// on the current locale. But almost all uses of these functions are for
34// locale-independent, ASCII-specific purposes. In WebKit code we use our own
35// ASCII-specific functions instead. This header makes sure we get a compile-time
36// error if we use one of the <ctype.h> functions by accident.
