Specifying the encoding for ExtractText

[DarrenWray]

I have an issue extracting text from a PDF that has been scanned and OCR'd in Greece. When I call ExtractText, the string returned includes a bunch of undisplayable characters meaning that although I can cut and paste the contents from Adobe Reader, I can't get at from within my software.

Is there a way to specify the codepage or encoding of the string returned by ExtractText or do you have any alternate advice?

Many thanks in advance,

Darren.

Hi Darren Wray,

Thank you for your letter.
Spire.PDF takes the Unicode as the default encoding. At present, it does not support specifying the encoding.
Anyway, could you please share your sample PDF document to help us look into it?

An example page is attached. I can cut and paste from this document in both Adobe Reader (windows and mac) and the mac preview app, but as shown in the screenshot in Example.zip the values returned are unintelligible.

Thanks in advance,

Darren.

Dear Darren,

Thank you for providing the sample.
When I copy the content directly in Adobe or extract text in Adobe, the content is still incorrect. Just see the space between the characters.

Actually, the text in your screenshot is pretty accurate - please see the attached showing your screenshot and the PDF side by side.

OCR quality aside, is there a way to get the text from this PDF without what appears to be codepage errors?

I'm not sure if it is related but when I look at the fonts used in the PDF, the encoding is set to custom, this seems to be a common trait amongst the PDFs that I can't process.

Any and all help appreciated,

Darren.
