Hi,

If I try to extract words from a pdf file, the special Turkish Characters are missing.

I don't have the source codes. It's clear that the extracting functions are skipping them while extracting.

Is there any solution for that?

Thanks

Hi Ingo,

I searched but I couldn't the solution. My code is below. Could you please fix that?

Thanks

    PDFLibrary := TQuickPDF0721.Create;
      err := PDFLibrary.UnlockKey('my key');
      err := PDFLibrary.AddSubsettedFont('Times New Roman', 13 ,'ĞŞİğış');
      str := PDFLibrary.ExtractFilePageText('C:\OCRTest\TXT\gk2.pdf', '', 1, 3);

memo1.Lines.Add( Utf8ToAnsi(str ));

Well, what is missing? Are they some other character or just not showing up? Based on your code you are converting an UTF-8 encoded string to Ansi. Now depending on that function, your Turkish characters are probably being stripped since they are not part of the Ansi character set. So debug your code and see if str has the correct characters before you call Utf8ToAnsi which is most likely stripping them.

Wheeley,

They are missing. I debuged millions of time. They are just missing. If I get any other character such as a box or something, I can find a way to convert. But they are missing.

I sent a message through the official support link with the samples a week ago about this problem. But no answer. I just received an automatic "your message received" email. That's it.

Very interesting..!

Be patient. They will get to you. Right now they are trying to wrap up a new release and need to fix all the stuff they know is broken.

What is your case number? Do you mean no answer at all or just no bug fix provided?

There is special function called GetSubsetString().

This function remaps Unicode characters that were added to the font subset to the corresponding character codes assigned to the glyphs in the subsetted font.

Please try attached code snippet. Hope 'ouput.pdf' contains what you need.

var
QPL: TQuickPDF;
t, s: string;
begin
QPL := TQuickPDF.Create;
try
    with QPL do
    begin
      t := UTF8Decode('ÄžÅžÄ°ÄŸÄ±ÅŸ');
      AddSubsettedFont('Times New Roman', 13, t);
      s := GetSubsetString(t);
      SetOrigin(1);
      DrawText(100, 100, s);
      SaveToFile('output.pdf');
    end;
finally
    QPL.Free;
end;
