[jira] [Comment Edited] (PDFBOX-2252) PDFTextStripper has problem
with bilingual documents
[ https://issues.apache.org/jira/browse/PDFBOX-2252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14629760#comment-14629760 ]

----------------------------------------------------------------
I am currently reworking the PDFTextStripper and did some changes for the whole RTL/LTR problem.
Unfortunately I had some technical Problems with my IDE, so the rework of my code was in another style format and the requests of two tickets from PDFBox run into each other. 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.

> 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.
