There's an easy solution to stop worrying among input, iosevka, source code pro, consolas, and the like: https://en.wikipedia.org/wiki/Andalé_Mono

    $ brew tap homebrew/cask-fonts     # You only need to do this once!
    $ brew install font-andale-mono

Of course, most other recommendations in this thread are available as well:

https://github.com/Homebrew/homebrew-cask-fonts/tree/master/...

These land in the same folder as user installs through Font Book. Using homebrew makes moving to a new system as easy as bundling the Brewfile.
