Andreas Lehmkühler resolved PDFBOX-1424.
----------------------------------------
Resolution: Fixed
Fix Version/s: 1.8.0
Assignee: Andreas Lehmkühler
I fixed the issue in revision 1404690.
The method TextNormalizer.makeLineLogicalOrder reordered all characters
including ligatures byte by byte which broke all ligatures.I eliminated the
usage of that method and replaced it with a simple descending loop.
I attached the fixed result.
> Wrong glyph (Persian) is used in extacted text instead of the original glyph
> (Persian) in PDF file

> Hi
> I am very new to PDFBox and I am dealing with Persian PDF files. When I
> convert Persian PDF files using PDFBox-app, some Persian glyphs like م are
> displayed wrongly in the extracted text. For example, the word "هستم" in
> Persian is extracted as "هستن" and "من" in Persian is extracted as "هن".
> Also, the word "سلام" is extracted as "سالم". By the way, I have tested
> extracting text from a complete Persian PDF file with multiple pages; the
> result is disappointing. Actually, it is totally wrong. Please let me know if
> I should upload an example Persian PDF file.
