Just download and put into your ~/.fonts dir and run fc-cache -vf
If you're using urxvt add something like this to your ~.XRessources or ~/.Xdefauts:
URxvt*font: xft:Monaco for Powerline:regular:size=8 URxvt*imFont: xft:Monaco for Powerline:regular:size=8 URxvt*boldFont: xft:Monaco for Powerline:bold:size=8 URxvt*italicFont: xft:Monaco for Powerline:italic:size=8 URxvt*boldItalicFont: xft:Monaco for Powerline:bold:italic:size=8
Make sure your run xrdb -merge ~/.Xresources
afterwards and close all urxvt terminals.
Thank you !!! Tried tons of things, and that finally worked for me.
I'm not an expert with fonts, but I have a slow terminal due to heavy zsh/tmux/vim confs, and one way to make that faster would be to disable xft. I can't run urxvt if I just drop out the "xft:" part of your lines, do you have an idea how to do that ?
