I've been using Fira Code for my font in BBEdit and ligatures have been supported with no additional action on my part. (In fact, I don't know how to turn them off). Anyway, I bought a new font, Berkeley Mono [1], and installed the version with ligatures. To my surprise, they aren't showing up. Is there anything I need to do on my part to get them to show up? I plan on writing the authors to see if they have any thoughts.
Just to test, I did try the font in iTerm, and the ligatures do work when I check the Use Ligatures check box.
