EugenePig updated PDFBOX-2409:
------------------------------
Attachment: THESSALONIANS.line - golden.txt
I uploaded a golden sample ” THESSALONIANS.line - golden.txt”. It uses UTF-16
encoding for easily debugging. I used Java Normalizer to normalize every
character first. For example, U+FC62 can be decomposed into U+0020, U+0650 and
U+0651. I also implemented an algorithm to determine what letter has the
diacritic by distance and how many diacritics the letter already has. The
algorithm is too complex. Therefore I don’t recommend it. That is why I
reported the issue and hope someone can fix it. Except diacritic issue, I found
another issue about Arabic PDF. A few letters are different from the original
PDF in my sample, such as the rightest letter in the second line. I think it is
Adobe’s issue. So I didn’t mention it in this issue report. I had asked that
issue on Adobe Communities. However I don’t get any solution. Please refer to
