Just download and put into your ~/.fonts dir and run fc-cache -vf
If you're using urxvt add something like this to your ~/.Xresources or ~/.Xdefaults:
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 to run xrdb -merge ~/.Xresources
afterwards and close all urxvt terminals.
After hours of searching found this font, which worked with gedit and sublime....Awesome....
