This discussion has become quite "surreal".
In the meantime, I and other people who have the need to write about these
characters have, with more or less encouragement from the Unicode Editorial
Committee started to use the terms "Supplementary Planes", "Supplementary
Characters" etc. This view has now also taken hold in WG2 and is being
reflected in part 2 of ISO 10646.
With that, the discussion is effectively settled - except for the fun of
continuing it ad inifinitum for its own sake. However, continuing it on
this list carries a certain element of mis-information with it, as the
question of the official terminology is no longer an open one. Please bear
this in mind, and help esp. novice readers on the list understand that this
is now a hypothetical speculation.
Thank you.
