How do you show the extended ascii table on C using Xcode?

Question

I'm programming on Xcode in C language. I've tried using a for loop to see which characters would I get for each number like this:

    printf("Lista of caracteres: \n");
    for (i=0;i<256;i++){
        printf("Caracter %d: %c \n", i, i);
    }

but starting from 128, I'm getting different results from the regular ascii table.

Lista de caracteres: 
Caracter 0: � 
Caracter 1:  
Caracter 2:  
Caracter 3:  
Caracter 4:  
Caracter 5:  
Caracter 6:  
Caracter 7:

What can I do to get the character "é" (130 on ascii table), for example?

I just now realised I'm asking how can I use the extended ascii table on C language using Xcode.

Answer 1

You have to use wprintf instead of printf and set the locale as shown below:

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

int main(void) {
    setlocale( LC_ALL, "en_US.UTF-8" );
    for (wchar_t i=0; i<=255; i++) {
        wprintf( L"Caracter %d: %lc\n", i, i);
    }

    return 0;
}
