Please copy the qu.orth file to quz.orth http://cgit.freedesktop.org/fontconfig/tree/fc-lang/qu.orth There are many variants of Quechua and it is important to be specific with three-letter codes.
instead of renaming?
renaming would work too, but I assumed someone else was depending on qu.orth version.
In fact it depends on the locale. once languages based on Quechua moving to 3 letter code for their locales, we can remove it safely. done anyway.
