------------------------------------------------------------------
The "-force" option is a documentation leftover, there's a fresh issue about
it, PDFBOX-4369.
There is no option to process each page by itself. Apache Tika (which uses
PDFBox) has it, I know it because we discussed it maybe a year ago. I can't
find it on [https://tika.apache.org/1.19.1/gettingstarted.html] so maybe it
isn't available on the command line, only programmatically.
You could also modify ExtractText for yourself. You first get the number of
pages (document.getNumberOfPages()), and then call `setStartPage()` and
`setEndPage()` for each page and run `writeText()` several times. Note that the
page numbers are 1-based here. (0-based at some other places)
I could also implement it for ExtractText, it would make sense for people who
need this and can't change the code. Main problem is that I'd need a good name
for the option. (Not "force").

> Key: PDFBOX-4367
> URL: https://issues.apache.org/jira/browse/PDFBOX-4367
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 2.0.12
> Environment: Mac OS X Sierra
> Reporter: Peter Johnson
> Priority: Minor
>
> Able to repeat with command line. Unfortunately, the only files that repeat
> this are from a customer, and contain sensitive information. The file opens
> without error in Acrobat Reader and Mac Preview. The desired result is that
> any corrupt portions of the PDF are skipped, so that we can use what text is
> extractable.
> Unfortunately, I still get an error when using the -force option.
> We get the following stack trace:
> {code:java}
