Tilman Hausherr commented on PDFBOX-3674:
-----------------------------------------
Here's a reduced file.... it allowed me to have a look despite having no clue
about arabic.
To clarify:
"fatha" = 064E = looks like an accent, the diacritic
"reh final" = FEAE, the non diacritic:
http://www.fileformat.info/info/unicode/char/feae/index.htm
Doing an output character by character at the beginning and at the end of
{{handleDirection}} shows that the order gets reversed.
> Incorrect ordering of fatha -- potentially indicative of larger issue with RTL

> On TIKA-2257, [~ccreutzig] shared a file that triggers PDFBox to flip the
> order of the fatha. I suspect this is happening in {{normalizeAdd}} within
> PDFTextStripper, but I'm not familiar enough with the code to diagnose and
> fix.
> I confirmed this is still happening in trunk.
> Triggering file and the start of a diagnosis is available on the Tika issue.
