Both string types will probably be fully supported on unicode supporting
platforms. The point is what the RTL uses. It makes sense to take the
encoding closest to the system, to at least allow minimal conversion
scenarios.

Yes. Note that what I say goes for the RTL, since obviously, in the core
library, speed and reducing dependancies is the most important. 

I don't mind if some XML lib or so is is always either UTF-16 or UTF-8
(depending on pedigree).
