Afaik none, except in Delphi it is default. In FPC it is a beta feature,
waiting for the codepage ansistring (which is being worked (*) in the branch that you
name), before the (very massive!) rtl changes, and the option for
unicodestring to be the default type become reality.
The actual form of the RTL changes and default types has not even been
decided. There are various opinions, but no decision has been taken.

Never used it. I use FPC's XML routines, even with Delphi.
