Andreas Meier commented on PDFBOX-2252:
---------------------------------------

I created a small test: atest.pdf


By the way: I also tried to use wikipedia as source for 
testcases(wikipedia_dl_lyric_test.pdf), but I couldn't evaluate the file since 
there is a problem with the extraction of (non-visual) overlapping characters. 
Is there already a ticket for (non-visual) overlapping character extraction 
problem?
(see: "This is the story of my life and = (waḥabbī my love".  The end of the 
extracted text is mixed up)

Sorry for my bad english...

> 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.
