How can that work for string constants ? Will they in fact (virtually) change
their encoding when DefaultSystemcodepage is different ?
It depends.
For a test I did result := StringCodePage('äü');
This results in a 0 which is CP_ACP, which is supposed to mean "in fact its
the value of DefaultSystemcodepage", which in my test in Linux is 65001
which means UTF8.
For string constants there are slightly different rules. There the result
depends on the {$codepage} directive of the source file.

Of course in this test it's correct. But if I start the executable in a
system that imposes another value of DefaultSystemcodepage or if it is
compiled in a way that results in the constant strings to be coded in another
way than 65001, what will I see ? (Right now I don't have a Lazarus
installation on Windows at hand).
Again, see
