Marc Reichman commented on PDFBOX-6054:
---------------------------------------
Thanks [~tilman] for the response. Could you give me a rough sketch of how to
implement such an override class, where it links into the API? I can look into
the documentation but if it's easy, I would appreciate a quick sample.
"The unicode is available, but it's wrong" – can you expand on that please?
What exactly is Chrome/Edge doing?
Thanks for your time.

> Project: PDFBox
> Issue Type: Improvement
> Components: Text extraction
> Affects Versions: 3.0.5 PDFBox
> Environment: Linux / JDK 21 / Docker
> Windows / JDK 21
> Reporter: Marc Reichman
> Priority: Minor

> With the attached PDF, there is plenty of gibberish in the text extraction. I
> have seen other issues mention this, but in this particular case it displays
> perfectly fine in Edge or Chrome. I have opened it in the pdf debugger but
> it's hard to figure out what I'm looking at.
>
> The pdftotext tool from xpdf generates the same. Interestingly, the pdffonts
> tool does not show any fonts as "problem".
>
> I understand this will happen and it's due to pdf generation bugs, not
> including proper unicode translators, etc. but I am curious, could we check a
> property or get a specific exception when unicode mapping is not available?
> I'm not sure if that's overcorrective; i.e. unicode mapping failures is a way
> of normal life.
