Using Font Awesome in the Emacs mode line

Font Awesome icons in Emacs mode-line

I installed Font Awesome and uses it to make my Emacs mode line look cool:

  • Use the align-left icon for auto-fill-mode.
  • Use the thumbs-up and thumbs-down icons for flymake status (we need to reimplement flymake-report-status to make this happen).
  • Use the tags icon for gtags-mode.

Requirements: diminish.el - I installed it from MELPA.

Since I don't specify the font anywhere this probably only works because Font Awesome is the only font providing those Unicode slots.

Is there away to specify font for individual characters in the mode line?
