+Pango
+=====
+
+Description
+-----------
+
+This patch adds pango support for the status bar.
+
+I find pango a better alternative than xft because it supports chains of fallback fonts
+out of the box, so you can use -for example- iconic fonts as your second family: "DejaVu
+Sans, Icons 8". The Icons family is a non-overlapping merge of Awesome and Ionicons fonts
+I've made for my statusbar. In case you're interested:
+
https://aur.archlinux.org/packages/ttf-font-icons/ (there is a cheatsheet with the icons
+and their unicode points linked there).
+
+This is not achievable using xft without further effort. Don't be mislead by the fact that
+fontconfig understands descriptors like "DejaVu Sans, Icons-8" or even font sequences
+defined as alias in your fonts.conf. xft will pick one font once and for all, not on a
+char-by-char basis.
