+    System Fonts
+
+    This file lists the font families that will be used by default for all supported glyphs.
+    Each entry consists of a family, various names that are supported by that family, and
+    up to four font files. The font files are listed in the order of the styles which they
+    support: regular, bold, italic and bold-italic. If less than four styles are listed, then
+    the styles with no associated font file will be supported by the other font files listed.
+
+    The first family is also the default font, which handles font request that have not specified
+    specific font names.
+
+    Any glyph that is not handled by the system fonts will cause a search of the fallback fonts.
+    The default fallback fonts are specified in the file /system/etc/fallback_fonts.xml, and there
+    is an optional file which may be supplied by vendors to specify other fallback fonts to use
+    in /vendor/etc/fallback_fonts.xml.
