I think you have to use a different font (the system only supplied
8x16, 8x14 and 8x8 fonts and for 720x400 you want 9x16 fonts).  If I
remember correctly, VGA would duplicate the rightmost column if the
character's code is between 0xB0 through 0xDF (this is hardcoded
knowledge about the so-called graphical characters) and for other
characters, that column is left blank.  Perhaps we need to implement
that in scr2png?
