This is not possible, since you don't control OS + headers. Most stuff will
come from the outside in the system encoding.
This way you can do the whole app in the system encoding, and only face
conversions when outputing to the GUI, which is (relatively) infinitely slow
You did nail a big problem though, and a weakness in Delphi's design.
What to do with classes that are used both straight and in the GUI?

If you want to be the lowest common denomitor and ask nothing from the 3rd
party packages, it is the best to stay with Ascii.
