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.

Your code seem good, but QuickPdf have problems with UniCode. I think Debenu is Working on it.

Perhaps the russian font isn't the problem?
How the pdf was made? With a free pdf-printer-driver like PDFCreator?
If it's an old version (using GhostScript before version 8.15) this is normal.
Does your extract result look like this here:
   !!\"!\"#
\" !$%%#%%
&    $%#'
()*+   *,-* ./*\"-

* + * -0 * 12\"
! \"\"\" # \"$
!3 (1 3# (1 4!'56
   - !3 (1 3# (1
7- !$3# (1
8+ * 8+
9 ** *    7
-:-\"
;*:
7+ *<+=
\"
&-- =
%%%%%%$
=
