How do you distinguish between D/O/0 on a 7-segments display?

• IIAOPSW 5y ago
  d/o/0 One of the compromises you have to make to get 7 segment writing system is that you won't always have capital and lower case options. Rather, some letters can only be written lower case, some only upper case, some both, and some sort of both but one of the cases conflicts with a different glyph (eg lowercase l and i). Eliminating case entirely and just having one symbol per letter is fine since capitalization isn't encoding much anyway. Another compromise/hack you can do is accept 1337 5p3ak as de jure spelling. So the number and letter characters are literally the same, and reading them as one or the other depends on context (or perhaps a special "this is a number" glyph like "#"). I admit some of the transpositions into a pure 7 seg alphabet feel like shoes that are slightly too tight. But we can break them in with time!
