Oh... I wonder what could we do if we had these fonts at the dawn of the personal computer.
Wait! We had them!
On the Apple II, the Magic Window word processor, could use a 70-column mode with the graphics screen and a font that was 4 pixels wide. It was 7 pixels tall, but nobody made a big deal out of that. I am quite sure I had proportional fonts that could fit in a 4x5 matrix in my developer toolbox (I did lots of courseware in the mid-80's that ran on Apple IIs). Using similar fonts, Atari and C=64 computers could do 80-column text screens with this same approach (both could do 320 pixels per scan line, while the II did only 280)
I used to have a Romanian ZX 81 clone in the early 90s, on which I could somehow boot CP/M which was really not meant to run on that machine in which there was an editor called tword that rendered characters in 4x7 pixels to have double column width (the native mode was 8x8 IIRC). A friend of mine hacked this editor to be able to display letters with acute accents so that we could write in Hungarian (he replaced some special characters). We were 11 or 12. I know, "cool story bro" :)
In Brazil we did similar things with accents, but Portuguese is no match for Hungarian in that regard. Also, my grandpa taught me Rovasirás and I made a font (Apple IIs had a nice hack for graphical fonts) for it.
I would like to know more about that ZX-81-like computer. We had something like it here, one that could do 192x256 pixel graphics.
