Fira code symbols in emacs. You need to grab the Fira Code Symbol font for this to work. https://github.com/tonsky/FiraCode/files/412440/FiraCode-Regular-Symbol.zip

@alphapapa Awesome job as always. However, the (set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol") part makes this conflict with all-the-icons. Is there a way to just use like a

(propertize (cadr regex-char-pair) 'face `(:family "Fira Code Symbol"))

when composing the region?

I don't use this, and I don't think I ever have. I just clicked the Fork button on the Gist years ago in case I wanted to use it someday. See the Revisions list.
