Pushing some more in this direction, my code below (with Amiri-Regular.ttf being
in the same directory) hyphenates the second and third "blabla" (consistent with
Yannis' reminder that the first word is not hyphenated) but only hyphenates in a
single place (the first one) in the sequence of ^^^^xyzt afterwards.
