Well, I no longer maintain ttf2pk due to time constraints.  And

Yes, there have been some efforts to do that:


I've never used it, nor do I know the status of it.

It's not a trivial job.  Reason: FreeType 2 no longer contains
OpenType support.  The special case of handling vertical
representation forms for CJK characters had to be implemented directly
in ttf2pk (this is, parsing the `vert' feature in the `GSUB' table).
Alternatively, the ICU library (as used by XeTeX) might be used for
it, but I'm not sure whether this is the right solution since it is
such a large library for such a small problem.
