That doesn't sound right. Try this program:

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

int main()
{
        int c = 0xC4; /* A umlaut in latin1 */

        setlocale(LC_CTYPE, "C");
        printf("%c is %sprintable\n", c, isprint(c) ? "" : "not ");
        setlocale(LC_CTYPE, "en_US.ISO8859-1");
        printf("%c is %sprintable\n", c, isprint(c) ? "" : "not ");
        return 0;
}
