How to use symbols of extended ASCII table in C?

问题

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?

回答1:

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("\u2500\u2501\n");
}

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