ImportTool do not work in Czech locale

[wlandgraf (Wagner Landgraf)]

I don't understand how AnsiLowerCase works and AnsiCompareText is not. Both rely on low-level Windows API functions. Can you give some concrete example?

@Zdenek_Vasku

For example IntProcHeading and intprocheading are different strings and AnsiCompareText do not return 0

The only example you provided is not sure. The following code shows "0":

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(AnsiCompareText('IntProcHeading', 'intprocheading').ToString);
end;
