Stockholm subway had a nice font. Digital version is called esseltube. https://sv.m.wikipedia.org/wiki/Esseltub https://sv.m.wikipedia.org/wiki/Esseltub

  That's a printed font though. BTW, Stockholm's subway used to up until very recently have dot-matrix LED signs with what I think did a neat embedded-programming trick. They could switch between a static message and scrolling text, but the scrolling text was slanted. I think the slanting was done by varying the timing for each row of LEDs. The bottom row was scrolled first, then the next above it after a short delay, and so on. I have been thinking of trying that trick for making scrolling text legible on a keyboard with backlit keys in a traditional row-staggered configuration. But I would first need a keyboard PCB for DIY with individually addressable LEDs.

    Interesting. I think the easiest way would to have each row on its own shift registers. It'd be trivial but if each pixel was on LED you could only slant at 45° intervals, which would be annoying. Maybe make each pixel 2LED×1LED (vertical). This would be the equivalent of shifting it by adding an offset to the characterset bitmap that depends on the position vertically in glyph.

    This italic scrolling was pretty standard on any LED sign in the 80s and 90s. I always assumed that, rather than a stylistic choice, it was just caused by the lines updating one after another because of update or display multiplexing speed.
