----------------------------------------
which version of PDFBox are you using? Is that an enhancement/addition to
PDFBOX-2252?
> Lack of Bidi (Arabic / Hebrew) test reordering in text extracted with PDFbox
> ----------------------------------------------------------------------------

> Key: PDFBOX-3096
> URL: https://issues.apache.org/jira/browse/PDFBOX-3096
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Reporter: TOMER MAHLIN
> Attachments: PDFBox_HebrewExtractedText.PNG
>
>
> Rendering rules for Bidi (Arabic / Hebrew) text in regular Windows / Android
> / iOS environment and Adobe environment are different. Adobe expect text to
> appear in visual bidi layout while modern system are working with logical
> bidi layout.
> When text is extracted from PDF file it should be converted / normalized to
> logical bidi layout.
> Example:
> Assuming capital letters stand for Bidi letters.
> 1. In Adobe document you see: CBA
> 2. When you extract the content and display it in Notepad (or web browser or
> any similar tool) you will see ABC while the expectation is to see CBA.
> Assuming you have a real text with both Hebrew and English (or Arabic and
> English) characters the result display is completely ruined after text
> extraction. Moreover, even if we ignore the display and focus on text
> manipulation (search, comparison, concatenation etc.), it will fail if the
> same text authored in Notepad and extracted from PDF file are compared.
