Depends. The few last msgs kept me thinking, and if what I saw on the web
about Tiburon is correct, they simply control the type of ansistring in
tstringlist, and default let it be the system encoding. (default like in old
delphi). For unicodecontrols they set some new property or so to change it
to UTF8, and take the conversion penalties for granted.

This allows them to do 

  MyStringList.SaveToFile('SomeFilename.txt', TEncoding.Unicode);  

It has to be something like that, since if mystringlist always was
ansistring in whatever ISO encoding, that would be a pretty pointless
unicode control.
