Print ASCII box not working

Question

I am just trying to print a shape filled with filled ASCII boxes into the console, but the output is just garbage text. Here is my code:

#include <stdio.h>

const char shade_block[] = {
    "▒▒██████▒▒\n\
     ▒████████▒\n\
     ██████████\n\
     ▒████████▒\n\
     ▒▒██████▒▒\n\
    "};

int main()
{
    printf(shade_block);
    return 0;
}

And here is the output:

ΓûÆΓûÆΓûêΓûêΓûêΓûêΓûêΓûêΓûÆΓûÆ
         ΓûÆΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûÆ
         ΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûê
         ΓûÆΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûêΓûÆ
         ΓûÆΓûÆΓûêΓûêΓûêΓûêΓûêΓûêΓûÆΓûÆ

Picture of the code, if it's not displaying properly.

I am working in C, CodeLite IDE, WIndows 10 with MinGW-32. Thanks in advance.

Answer 1

Though RbMm and PeterJ's answers worked, I used tips from this StackOVerflow question and eventually figured out how to print the block as-is without any character-escaping or WriteConsoleW:

#include <stdio.h>
#include <wchar.h>              //For wprintf and wide chars
#include <io.h>                 //For _setmode
#define U_16 0x20000            //U-16 text mode, for the text blocks

const wchar_t shade_block[] = {
    L"▒▒██████▒▒\n"
    "▒████████▒\n"
    "██████████\n"
    "▒████████▒\n"
    "▒▒██████▒▒\n"
    };

int main()
{
    _setmode(_fileno(stdout), U_16); //set the output mode to U_16
    wprintf(L"%s\n", shade_block);

    return 0;

}
