Extract text from PDF problem with "fi" and "fl"

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I'm extracting text from PDF with Delphi XE and QuickPDF v.7. I've tried the v9.13 demo and the problem is the same. The PDF encoding id UTF-8. Language is Portuguese.

For the word:
 Identifique

I get:
 Identiﬁ que 

I've checked the Ord for each char (it's between paranthesis) and it looks like this:
(32)I(73)d(100)e(101)n(110)t(116)i(105)ﬁ(64257) (32)q(113)u(117)e(101) (32)

This is coming out directly from QuickPDF library as follows:

            QP.LoadFromFile(OpenDialog1.FileName,'');
            PageCount := QP.PageCount();
            for i:= 1 to PageCount + 1 do
            begin
              TextOutput:= TextOutput + ' ' + #10 + QP.ExtractFilePageText(OpenDialog1.FileName, '', i, 8);
            end;
            sl.Text:= TextOutput;

TextOutput is a Widestring.

Am I doing something wrong? This happens only for "fi" and "fl".

Thanks,
Miguel

	I've found that this issue only happens with PDF files generated by Adobe InDesign. It seems to be related with ligatures as this forum post describes: http://forums.adobe.com/thread/792075 Any workaround for this? Thanks

	QPL 8.xx has support for extracting ligatures. We would need to see the file to see why the problem PDF to see why this is happening. Andrew.
