Well, Hans has some code (in typo-mir.{tex,lua}), it does work but not
complete, might want to take that code and complete it, or of course
write a different implementation.

Currently, I'm using some python code, adapted from another project, as
an external OCP, it works for simple cases but don't handle explicit
BiDi marks and so, and is slow like hell. If any one interested I can
post it some where.
