Great, that looks very very promising. I will run various test cases and
come back when I finished. Maybe that code should make it, perhaps with a
different name, into quail.el?


I have to admit that this code is beyond me, while I more or less
understood the original iso-accentuate code, which worked with tables.

A last question then, for the sake of completion: you said the inverse
function would be trivial. In the case of the original iso-accentuate it
was. Would it be here as well? But as I said in my earlier mail I am
very happy with the accentuate version.

Thanks a zillon
