That only works if the codepage is known at compile time.
Let's say the user directs a program to "treat this file as $codepage".
Therefore, I need to read it as this codepage and fill internal data structures
with strings in that codepage, while keeping other operations in the system
codepage (so I can't just change DefaultSystemCodepage). Does that mean that
there is no way to do this with native strings?

Actually, there is a String type that is just that (at least according to the
wiki): RawByteString. Supposedly, it just accepts any dynamic codepage without
conversion. But it doesn't work for either of the cases here?
