Print braille fonts in ncurses

Question

I tried typing braille characters in ncurses.

This is my code:

#include <ncurses.h>

char *str = 
    " ⠁⠂⠃⠄⠅⠆⠇⠈⠉⠊⠋⠌⠍⠎⠏\n"
    "⠐⠑⠒⠓⠔⠕⠖⠗⠘⠙⠚⠛⠜⠝⠞⠟\n"
    "⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯\n"
    "⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿\n";


int main(int argc, const char *argv[]) {
    initscr();
    printw("%s", str);
    getch();
    printf("%s", curses_version());
    endwin();
    printf("%s", str);
    return 0;
}

Conclusion:

 ?~A?~B?~C?~D?~E?~F?~G?~H?~I?~J?~K?~L?~M?~N?~O
?~P?~Q?~R?~S?~T?~U?~V?~W?~X?~Y?~Z?~[?~\?~]?~^?~_

How to correctly display all characters?

Update: I also tried printf, which seems to work, addstrproduces the same output as printw.

If I change the locale with setlocale(LC_ALL, "");, I get the output:

  A B C D E F G H I J K L M N O
 P Q R S T U V W X Y Z [ \ ] ^ _
⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯
⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿

Answer 1

In some experiments, I found that it was probably wrong:

• C. ASCII. stdio, , . ncurses , , , ( ) .. :

  #include <curses.h>
  #include <locale.h>
  
  int main(int argc, char *argv[])
  {
      // initialize locale to system default:
      setlocale(LC_ALL, "");
  
      // now init and use curses ...
  

• , libncurses unicode. ncursesw ncurses, .
