+Description: Xft with fallback font support built on top of the Xft patch
+written by Quentin (http://lists.suckless.org/dev/1311/18279.html). The utf8*
+functions were written by Damian Okrasa for the MIT/X licensed
+(http://opensource.org/licenses/MIT) terminal emulator st
+(http://st.suckless.org/).
+
+With this patch, the "font" variable in config.h is superseded by the "fonts"
+variable which is a priority-ordered list of fonts that should be used to
+render text. Here's an example "fonts" definition:
+
+    static const char *fonts[] = {
+        "Sans:size=10.5",
+        "VL Gothic:size=10.5",
+        "WenQuanYi Micro Hei:size=10.5",
+    };
+
+At least one font must be specified, and a maximum of DRW_FONT_CACHE_SIZE fonts
+can be used.
