Here are the things you need to know about using any new font for Rubymine:
- It needs to be Unicode
- It needs to go into the $JDK_HOME/jre/lib/fonts directory
That is absolutely it. The last thing is the Monaco font, which I have attached for your downloading pleasure. It turns out DejaVu Sans Mono just isn’t as nice — however nice it may be — and Inconsolata XL doesn’t quite do it for me either.
