[jira] [Created] (PDFBOX-3833) Characters in wrong order

Christopher Creutzig created PDFBOX-3833:
--------------------------------------------

             Summary: Characters in wrong order
                 Key: PDFBOX-3833
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3833
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing
    Affects Versions: 2.0.5
            Reporter: Christopher Creutzig
         Attachments: ML_mathworks_unc2.pdf

The attached pdf file (which is page 3 of https://jp.mathworks.com/tagteam/89688_93050v00_JP_machine_learning_section1_ebook.pdf) shows multiple problems when reading with PDFBox in standard settings. This bug report in particular is about the Katakana ー being misplaced.

In the text block on the left, the second line starts with ターン. PDFTextStripper.getText returns text starting with タ ンー (i.e., adding a space after the first character and swapping the second and third one). This effect also happens at other places in the (complete) file.

The PDF itself at this point has [<03BB>43.9 <0294>156 <03EF>-24.5 ...]TJ, listing the characters in the proper order. Copy&paste using Apple's Preview.App also preserves that order.
