How to print "mailboxes for boxes" Unicode characters in C (Linux terminal utf8)?

Question

I am trying to display Unicode characters from (Box Drawing Range: 2500-257F). It must be standard utf8 (Unicode standard, version 6.2). I just can't do it.

At first I tried to use the good old ASCII characters, but the Linux terminal displayed in utf8 and there is no conversion (character?) Displayed in place.

Can anyone answer these questions:

• How to encode a Unicode character in a C ( style wchar_t) variable ?
• How to use escape sequence like 0x or 0o (hex, oct) for Unicode?

I know U +, but it doesn't seem to work.

setlocale(LC_ALL,"");
short a = 0x2500, b = 0x2501;
wchar_t ac = a;
wchar_t bc = b;
wprintf(L"%c%c\n", ac, bc);
exit(0);

:

#include <stdio.h>

int main (int argc, char *argv[])
{
    char block1[] = { 0xe2, 0x94, 0x80, '\0' };
    char block2[] = { 0xe2, 0x94, 0x81, '\0' };
    printf("%s%s\n", block1, block2);
    return 0;
}
