Jukka Zitting commented on PDFBOX-800:
--------------------------------------

We might consider enabling the sortByPosition option by default in PDFBox, as 
the performance impact isn't too bad (around 5% on some documents I tested 
with). Alternatively you can file an improvement request for Tika to explicitly 
set the option in its PDFParser class.

> I was told to move this issue to the pdfbox parser, so I hope this is the 
> right section.
> Vertical textboxes in pdf files are not extracted correctly (using the tika 
> library in C#).
> For example if there is a vertical textbox "hello" in a pdf file (!WITHOUT! 
> line breaks):
> H
> E
> L
> L
> O
> the parser returns 5 strings, each with a single letter, even there is NO 
> line break after every letter.
> Is there a option to avoid this problem?
