This char is 254 in ASCII Extended Table, and 25A0 in Unicode. If I run putchar(254) the terminal does not recognize the char, as I think it utilizes not extended ASCII.

printf("■ "); works for me - putchar('■'); gives me a warning about multi-character character constants. putchar(254); gives me a 'þ' character.
Also, make sure the terminal emulator you are using supports unicode.
