This does not work for me:
but this code, from the
Monoid repo works great, on all three fonts:
-webkit-font-feature-settings: "liga" on, "calt" on;
-webkit-font-feature-settings: "liga" off, "calt" off;
Not only does this enable ligatures, but when the cursor is on a line with a ligature it turns that one off so you can better see the characters. Not sure if you're aware of this, or if this code is officially supported.
Also, aesthetics aside, so far I am finding
Fire Code to have the dest character display. Little things like comments work better
