It depends.
There are two codepages. The real one and the one you tell the
compiler.
If you tell the compiler that the string literal is 8-bit system
codepage, it will copy it without conversion to the binary.
Otherwise it converts it to UTF-16.

For instance using {$codepage utf8} tells the compiler to convert all
your literals to UTF-16.

Without the {$codepage} the compiler preserves the real codepage.

StringCodePage on a literal is pretty useless. You should
use StringCodePage on variables.
