It is not possible to work with a ever changing encoding.

MyLabel.Caption := 'Lição';

How would that ever work with a ever changing encoding? It would not.

If you go to the real implementation level a changing encoding quickly
becomes unmanagable.

And what about the LFM files? In which encoding will they be? What if
you develop a software in one system and tryes to build it in another?

Ok, to go one step further: Has anyone ever seen a fully unicode
system which works with changing encodings? I beliave there exists
none, because this is not a good solution.

This is already necessary.

Delphi code can use the ansi routines, which could just call the
utf-16 routines with a string conversion, or you can implement every
routine twice to maximize speed.
