You still access internal Wine code page structures, I'm not sure why you
claim otherwise.

What's happend to the idea to use mlang_data?

And again: forget about Wine internal code page structures, that's the
implementation detail that's internal to kernel32/ntdll, that structures
should not be used outside of kernel32/ntdll.

Have a look how other parts in Wine call vtable members, the tests have
enough code samples.
