IntelliJ IDEA (version 2018.3.3) doesn't see the Monaco Linux font I installed despite all other programs being able to. I've tried using the solutions in this question but they either don't work, they're dangerous (breaks fonts in Ubuntu 14), or they're for other systems.
How can I get IntelliJ to use the font I want?
I have faced a similar issue. Solved it by using different types of TTF files of Monaco fonts. You can find them on GitHub.
