Yes, if the font is the same you can not be sure that it has not changed but
sometimes if it has changed you can be sure that it has changed. :)
In your case the font has not changed, so there is no need of more tests.

Then it seems this bug must be reassigned to some of the x server video drivers.
What is the type of your videocard? Can you attach the contents of /var/log/Xorg.0.log
What happens if you don't use Ctrl+Alt+F1 but rather exit X the normal way?
In order to work with 9x16 and 9x14 fonts the video card does a magic: for some of
the symbols (the pseudographic symbols) it uses the 8-th bit in each line as 9-th
bit. This magic is due to the fact that even the most modern cards are emulating
the old VGA hardware that was developed 20 years ago when only the 8-bit
technologies were cheap. Somehow X leaves the videocard in a mode when it doesn't
use the 8-th bit as 9-th and leaves the 9-th bit empty.

I suppose this was because of the way this font was loaded. I think if you put
FONT='lat1u-08.psf.gz' in /etc/default/console-setup the lines will not be broken.
If you start using framebuffer all lines will display correctly but the console
will use 8x16 and 8x14 fonts instead of 9x16 and 9x14. I don't know how the problem
you are experiencing can be fixed in the regular text mode.
