Tilman Hausherr commented on PDFBOX-2252:
-----------------------------------------
Yes, but it is risky to create something ourselves in a foreign language that
we don't understand. Other have failed at a similar task, see
[here|http://www.deseretnews.com/article/358133/MCDONALDS-NEW-BURGER-BAG-ANGERS-MUSLIMS.html?pg=all]
and
[here|http://www.independent.co.uk/news/world/europe/chanel-apologises-to-muslims-for-satanic-breasts-dress-1409011.html].
I also like taking PDF files "from the wild", they are more realistic and can
bring interesting surprises.

> Key: PDFBOX-2252
> URL: https://issues.apache.org/jira/browse/PDFBOX-2252
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 1.8.6, 2.0.0
> Reporter: Amir
> Priority: Critical
> Fix For: 2.1.0
>
> Attachments: PDFTextStripper.java.patch, test.pdf
>
>
> When the input document of PDFTextStripper is a combination of right-to-left
> and left-to-right languages, the output characters of one language is
> reversed.
> A sample bilingual pdf document is attached.
> PDFTextStripper has a variable "isRtlDominant" in "writePage" function, which
> is defined as follows: boolean isRtlDominant = rtlCount > ltrCount;
> This class clearly count the number of rtl characters and decide if the whole
> content should be revered or not. It's not true, it must operate on each
> word, not the whole document.
