That is required to let fontconfig know what the glyph coverage a font has.

I don't see what you really mean. in fact fontconfig do cache a font per file.

I don't know how often it happens though, they may see something like annoyance
in fontconfig without creating a cache before doing something on their
fontconfig-based applications. this is why fontconfig is going to create a
cache though.</pre>
