character - How to use symbols of extended ASCII table in C?

Question

I've been tried to print Extended ASCII characters:

http://www.theasciicode.com.ar/

But all those symbols were printed as question-character on the white background ?.

I use the following cycle to print that symbols:

for (i = 0; i <= 30; i++)
    printf("%c", 201); 

Question: Is there any way to print those Extended ASCII characters or not? Or maybe there is special library for these characters?

It's better to use unicode than extended ASCII, which is non-standard. A thread about printing unicode characters in C : printing-utf-8-strings-with-printf-wide-vs-multibyte-string-literals

But indeed you need to copy paste unicode characters..

A better way to start:

#include <stdio.h>

int main() {
    printf("u2500u2501
");
}

See https://en.wikipedia.org/wiki/Box-drawing_character#Unicode for unicode characters for this extended ASCII style box art..
