Font Famliy? Which Font Is Used on GUIs?

What font is used to display texts on URCap ProgramNode GUIs?

Actually it was bothering me recently.

It would be great to change font to something more programming friendly:

  • monospaced

  • with easily distinguishible characters, compare:

    • O o 0
      O o 0

    • 1 I i L l
      1 I i L l

    • 5 S s
      5 S s

    • 2 Z z
      2 Z z

    • ({[]})
      ({[]})

This is what Polyscope actually uses:
polyscope%20font

You can see, that it is almost impossible to recognize capital-O <> zero and capital-I <> small-L.

Can you tell me which font is that?

Not sure, but I would bet my money on Deja Vu Sans.

Seems like you were right about DejaVu Sans, but it also looks like that some languages use a different font, whish there were any info on that.

If you are pressed for time, then maybe you can use WhatTheFont Font | MyFonts

If that does not work, then you can find fonts by answering a series of questions at Identifont - 1: Serif or sans-serif?
