The problem is in framebuffer mode OF loads glyphs starting from 32 to
127 then any characters abowe 127 are displayed as white '?'. The
solution would be to use "set-font" to load a proper font to use with
grub. In non framebuffer mode cp437 is used by console then we can use
it to draw borders same as for PC.

Ahhh, I see you looked at first version of patch. Please take a look
at recent version of my patches.

For some reasons my OF sends \b && 127 (Del) sequence for backspace
key. It seems to be same sa ncurses console.
