Yes, you could. But as said you need tables to emulate them.  And I doubt it
is worth it?

What is the use of this record then?

 TSysLocale = record
    { Delphi compat fields}
    DefaultLCID,
    PriLangID,
    SubLangID  : Integer;

    case byte of
      { win32 names }
      1 : (FarEast: boolean; MiddleEast: Boolean);
      { real meaning }
      2 : (MBCS : boolean; RightToLeft: Boolean);
  end;

That leaves the MBCS and RightToLeft, of which MBCS has no meaning on *nix
(since if that changes, a lot more has to change?)
