[Alain] :
In the BMP the allocation was ordered at once per radical/strokecount as
agreed between CJKSV countries (so for the current BMP it is the easiest
script to order with this shape-oriented criterium that was agreed by
involved countries). We'll of course have to make insertions for additions.
That, we know.
But it would be easier to make insertions by contiguous chunks by
radical/strokecount than one by one for tens of thousands of other
characters. If code allocation is made with this in mind (whenever possible,
of course), that will be less of a nightmare for a good international default.
That's all what I'm saying. Seems obvious. Maybe it's not for everybody
after all.
