Thanks for your patch! :-)

however, see my comments, below...

Again, I'm not too happy with this. We already have a fontconfig
conditional block, below. So this code should go strainght in the else
clause.

Then, when/if (and *only* then) libass gains support for another system
font provider, we can think of changing it.

At worse, I'd prefer Vicente's solution.
