As I explained in my mail, this is wrong.

Some programs are broken.  This is a fact of life.  This should not be
an issue to discuss here.

  (They may be broken with AltGr.  They may be broken with deadkeys.)

I have no experience with MS programs; however, I doubt your
conclusion very much.

Who cares?  As far as it works…

If you have 400-keys keyboard — fine with you.  However, with Yorùbá,
this may be even feasible, since there are many Latin characters
excluded.

The approach I explained does not require AltGr.  It is just the logic
of combining a prefix key with a key producing a cluster.

P.S.  If it was not clear, the AltGr-keys in my initial message should
      produce combinations with U+0329.
