Tilman Hausherr commented on PDFBOX-4737:
-----------------------------------------
Re the file mentioned in PDFBOX-4549 ([^obfuscateTest_Duplicate_2_3.pdf]), that
one currently returns nothing, although Adobe has something.
If we'd do "strict" text extraction we could still hit files that are purposely
obfuscated, see the comment by mkl. IMHO this isn't the job of PDFBox. This
should be done by the caller.

> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 2.0.18
> Reporter: Jorge Spinsanti
> Priority: Major
> Attachments: noUnicodeMapping.pdf, obfuscateTest_Duplicate_2_3.pdf

>
> As it was discussed on https://issues.apache.org/jira/browse/PDFBOX-4549
> there are many PDFs where the text extraction is gibberish.
> Perhaps you can add two modes (strict/lax) to text extraction to avoid
> gibberish if not useful. Add a file to analyze the problem.
