So does that mean you don't have to also call the following two functions (which LCL does).

 SetMultiByteConversionCodePage(CP_UTF8);
 SetMultiByteRTLFileSystemCodePage(CP_UTF8);


So doing

   DefaultSystemCodePage := CP_UTF8;

is all you need to switch the RTL, FCL and the String data type to UTF-8?

If so, when why does LCL also call the above two functions?
