"Output" with special characters

Question

I am using the GCC compiler version 5.3 for the following program, written in Aptana:

#include <stdio.h>

void main(void)
{
    int positivo = 32767;
    int negativo = -32768;

    printf("%d +1 é %d\n", positivo, positivo+1);
    printf("%d -1 é %d\n", negativo, negativo-1); 
}

With the following output:

Already in the text block, with the following:

How should I proceed to have the characters displayed correctly ?

Answer 1

Probably need to use a setlocale() to allow the use of accented characters.

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

int main(void) {
    int positivo = 32767;
    int negativo = -32768;
    setlocale(LC_ALL,"Portuguese");
    printf("%d +1 é %d\n", positivo, positivo + 1);
    printf("%d -1 é %d\n", negativo, negativo - 1); 
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.

But it is no advantage because they already worked without the setlocale(). I couldn’t test in his condition to reproduce the problem.
