Problem with Russian text

Good day, guys.

I have a real problem when I try to extract PDF with a Russian language symbols, instead of it I have nothing (string = '';). In extracted data I have only latin and special symbols like #.,!"' and numbers.

Im tried to set AddTrueTypeFont and AddSubsettedFont, but I think that It for saving text in PDF file. Also I tried PDFLibrary.SetFontEncoding(2), but also got no luck...

Here is my code:

procedure TfrmBaseConvert.Button1Click(Sender: TObject);
var
PDFLibrary: TQuickPDF0715;
i: Integer;
temp1: TStringList;

begin
  PDFLibrary := TQuickPDF0715.Create;
  temp1 := TStringList.Create;
  try
  PDFLibrary.UnlockKey(- its my key -);
  begin
  PDFLibrary.LoadFromFile('C:\Documents and Settings\DENE\Desktop\HelloFromDelphi.pdf');
  PDFLibrary.SetFontEncoding(2);
  temp1.Clear;
  for i := 1 to PDFLibrary.PageCount do
  begin
  PDFLibrary.SelectPage(i);
  temp1.Text := temp1.Text + (PDFLibrary.GetPageText(2));
  end;

  end;
  finally
  PDFLibrary.Free;
  end;
end;

Please, help me. Thx a lot.
