Gavin has already said that these tables do not have to be that large.
In addition, for the above *three encodings*, you need only *one table*,
as the mapping between the three is algorithmical. The same applies
for other groups of encodings in the list.

It is easily possible to load these tables just on demand, so that
main memory is not affected unless they are needed (I have done
such an implementation). Also, it is not the designation of
ISO 10646 as a document character set that makes these
tables necessary.
