For a long time, I’ve just put on DejaVu fonts and been done with it. Generally good enough Unicode coverage for me. But I know it’s been years since DejaVu’s been updated, and I wonder what’s very common today.
[As for the terminal, I’m guessing it’s usually still the standard fixed Unicode fonts?]
The Unicode coverage of the Ubuntu font is not very big compared to Google’s Noto
Well it’s pretty much the entire point of Noto after all, so it’s probably hard to beat, from the website:
The name is also short for “no tofu”, as the project aims to eliminate ‘tofu’: blank rectangles shown when no font is available for your text.
