John Hewson commented on PDFBOX-2259:
-------------------------------------
No, the semi-space character isn't part of the text embedded in the PDF file.
The PDF contains additional "marked content" for accessibility, screen readers,
etc, which does contain the semi-space. Only PDFMarkedContentExtractor has
access to that character.
However, it seems like there may be a bug in PDFMarkedContentExtractor so
you're still getting the wrong result. I'll take a look soon.

> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 1.8.6
> Reporter: Amir
> Attachments: test.pdf
>
>
> In some right-to-left languages, compound words are separated using
> "semi-space" (please take a look at Unicode spaces:
> https://www.cs.tut.fi/~jkorpela/chars/spaces.html). When the input document
> contains these words, PDFTextStripper neglects semi-space character and
> concatenates words together.
