Teletext also has the “smooth” characters that have inclined lines. I’d need to take a good look at them to understand how to use them, but if you can lose the vertical precision, it’s OK, because you pack more in the horizontal axis.

As for Braille, the last Unicode standard added Kaypro’s 2x4 mosaics, so we can stop misusing Braille for that (a huge relief to me, because the banding that often happens always annoys me).
