     Fallback Fonts
 
     This file specifies the fonts, and the priority order, that will be searched for any
     glyphs not handled by the default fonts specified in /system/etc/system_fonts.xml.
     Each entry consists of a family tag and a list of files (file names) which support that
     family. The fonts for each family are listed in the order of the styles that they
     handle (the order is: regular, bold, italic, and bold-italic). The order in which the
     families are listed in this file represents the order in which these fallback fonts
     will be searched for glyphs that are not supported by the default system fonts (which are
     found in /system/etc/system_fonts.xml).
 
     Note that there is not nameset for fallback fonts, unlike the fonts specified in
     system_fonts.xml. The ability to support specific names in fallback fonts may be supported
     in the future. For now, the lack of files entries here is an indicator to the system that
     these are fallback fonts, instead of default named system fonts.
 
     There is another optional file in /vendor/etc/fallback_fonts.xml. That file can be used to
     provide references to other font families that should be used in addition to the default
     fallback fonts. That file can also specify the order in which the fallback fonts should be
     searched, to ensure that a vendor-provided font will be used before another fallback font
     which happens to handle the same glyph.
+
+    Han languages (Chinese, Japanese, and Korean) share a common range of unicode characters;
+    their ordering in the fallback or vendor files gives priority to the first in the list.
+    Locale-specific ordering can be configured by adding language and region codes to the end
+    of the filename (e.g. /system/etc/fallback_fonts-ja.xml). When no region code is used,
+    as with this example, all regions are matched. Use separate files for each supported locale.
+    The standard fallback file (fallback_fonts.xml) is used when a locale does not have its own
+    file. All fallback files must contain the same complete set of fonts; only their ordering
+    can differ.
