This example works like that because it's running in C locale always.
Try something like this:

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

int main () {
        char s[] = "ni\xc3qo"; /* 5 bytes , not valid utf8 */

        setlocale(LC_ALL, "");
        printf("|%.*s|\n",3,s);
        return 0;
}


I get different (and undesirable) effects depending on LANG.
