I understand the theory, but that's not how the code currently works,
AFAIU. It will have to be modified to support this. I also suspect
that some support from the font back-end (a.k.a. "shaping engine")
will be required, perhaps in using special APIs or activating some
special options, in order to get all this working as expected.
