Andreas Meier commented on PDFBOX-2252:
---------------------------------------
I am currently reworking the PDFTextStripper and did some changes for the whole
RTL/LTR problem.
Unfortunately I had some technical Problems and a rework of my code.
Furthermore I had to add the formatting style of the pdfbox later on. For this
reason I copied the RTL/LTR changes from my working space to a pulled instance
of PDFTextStripper (from pdfbox svn)
Can you check if the patch I posted resolves this problem?
In my default workspace the extraction of the text works.

> 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.
