Yeah, so there's the question. I wondered if it was possible to use the Ubuntu font in the terminal. I know how to change the font, but using anything except a monospace font doesn't really work very well. Is there a way to use a non-monospace font where it looks ok?
Is it possible? Yes. (However, not for Konsole - it prevents you to select non-monospaced fonts.)
Does it work well? No. Output formatting is relying on a monospaced font to make it look as designed (tabular output for example).
