VisualizaçõesWhy 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. 
I've checked:
- tried compiling without setlocale, same result
- the terminal itself can print the character, I can copy-paste it to terminal from text-editor, it's gnome-terminal on Ubuntu
- GCC version is 4.8.2

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);
}
