John Hewson commented on PDFBOX-2259:
-------------------------------------
Ok, I see the problem. The PDF text itself doesn't contain the joining space
character which is needed, copying and pasting gives the wrong result too.
The text which you want is in the PDF though, as "marked content" which is used
for accessibility. The PDFMarkedContentExtractor class can be used to extract
this text. Perhaps try that.

> 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.
