John,
You just discovered one more shortcoming of UniScribe. As you say, the
authors did not consider this particular case. I suppose it will be fixed
sooner or later.
I don't see how this affects the discussion, though. UniScribe and most
current fonts do not process the simple case of Holam correctly, and we
don't take it to mean there is something wrong with the Holam.
