------------------------------------------------------
I'm not sure what is the equivalent character for semi-space. I think it's a
"ZERO WIDTH SPACE". For example, check the attached document, it contains
"نیمفاصلهها", this word is in Persian and compounds of "نیم" + "فاصله" + "ها"
which have been concatenated via semi-space ("ZERO WIDTH SPACE"). The output of
PDFTextStripper is "نیمفاصلهها". It's incorrect.

> URL: https://issues.apache.org/jira/browse/PDFBOX-2259
> 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.
