Ported the translation code, which again proved a little simpler than expected; the test application is working like a charm. The only unexpected thing was that although I thought I'd be looking for properties which were tkString (previously tkWideString), it turns out that I needed tkUString; presumably the TypInfo.pas unit is not quite as "Unicode-everywhere" as the rest of the VCL and RTL. My guess is that this is a result of its hooking into Windows fairly closely, so being dependent on Windows types rather than Delphi types, so tkString has some specific relationship to a Windows string type.
