Sure. that sounds nice :)

So I guess the language coverages of
ISO-8859-{1-5,7,9,10,13-16} may works similarly right?

I see. I don't mind which ranges should be used. my point
here is to have a bit more strict prioirty-sets to apply the
fontconfig config files efficiently.

Correct if it's spent randomly. I didn't mean that
though. and that's also why I'm suggesting to have more
clearer definition in the policy to not make more
breakage. at least to avoid it in Fedora.
I'm at the position where to have minimum-sets of the
configuration in upstream. which doesn't mean to have a
starter kit nor all-in-one. but just leave to each fonts
packages to have one. generally speaking, ideally if a kind
of the font installer can create/install the certain
fontconfig configuration file into the system, that would be
really nice. once we have more strict policy we could have
that feature perhaps.

I see. so what's the _default font_ means in the policy
then? I was assuming if it's available at the system. thus,
focusing attention on comps then though.
Anyway, if we have obvious definition for that, I'm fine
then. possibly everything goes into the higher priority will
messes up you know. this is the main reason why I'm trying
to make the font packages better, making the fontconfig
configuration files machine-auditable to reduce the
check-cost.
