Why Unicode characters are not displayed properly in terminal with GCC?

I've written a small C program: 

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

int main() {
    wprintf(L"%s\n", setlocale(LC_ALL, "C.UTF-8"));
    wchar_t chr = L'┐';
    wprintf(L"%c\n", chr);
}

Why doesn't this print the character ┐ ?

Instead it prints gibberish. unicodetest

I've checked:

wprintf is a version of printf which takes a wide string as its format string, but otherwise behaves just the same: %c is still treated as char, not wchar_t. So instead you need to use %lc to format a wide character. And since your strings are ASCII you may as well use printf. For example:

int main() {
    printf("%s\n", setlocale(LC_ALL, "C.UTF-8"));
    wchar_t chr = L'┐';
    printf("%lc\n", chr);
}
