Why wouldn't it print a rectangular box? The text editor prints a rectangular box because there isn't a character for a backspace its an escape sequence like a tab or a new line. If you look at that same file in a hex editor you will see the hexadecimal value of a backspace so it is there. But your text editor, or any text editor for that matter, dosn't have anything to represent a backspace on screen so a black box is used.
