But how would that avoid the confusion? Just the opposite. It would add 
even more because the conversion avoids at least some of the problems.

The main problem realy is, that (some!) stings are completely omitted 
when they are Ansi where UTF-8 is needed. If I do it the other way round 
(convert my code to UTF-8 and use these strings for RTL routines) I 
immediately see that something is wrong with the encoding ("funny" 
characters are displayed). But when nothing is displayed I have no idea 
why that happens.

That's the correct question. How do I know which routine is from where? 
And why am I forced to think about such things when programming? In 
Delphi I am not.
