no, _ctype_(for is*) and rune(for isw*) *must* be separated, example:

#include <ctype.h>
#include <locale.h>
#include <stdio.h>
#include <wchar.h>
#include <wctype.h>

int
main(void)
{
        setlocale(LC_ALL, "en_US.UTF-8");
        printf("isspace:%d\n", isspace((unsigned char)0xA0));
        printf("iswspace:%d\n", iswspace((wchar_t)0xA0));
}

this code print:

isspace:0
iswspace:1

apparently ctype table and wctype table *differ*.


see following FreeBSD's PR:

(they introduced __mb_sb_limit variable, but i think it is kludge)


very truly yours.
