SUMMARY

When "copying and pasting": Okular prints line breaks that don't really exist,
and therefore some lines are "broken" :(

There are problems copying and pasting from a PDF file to e.g. a text editor,
or a terminal emulator. I attach the PDF file, and the ODT source file. The
problem doesn't happen using Adobe Acrobat.


STEPS TO REPRODUCE

1. Open the pdf file.
2. Copy the text.
3. Paste the text in a text editor.


OBSERVED RESULT (the text after copying and pasting from the PDF file to a text
editor or a terminal emulator)

ZERO*)
echo "0";;
*ONE\
TWO\ *) echo "1 2" ;;
*ONE\
THREE\ *) echo "1 3" ;;
*ONE\
FOUR\ *) echo "1 4" ;;
ONE*)
echo "1" ;;


EXPECTED RESULT

ZERO*) echo "0";;

*ONE\ TWO\ *) echo "1 2" ;;
*ONE\ THREE\ *) echo "1 3" ;;
*ONE\ FOUR\ *) echo "1 4" ;;
ONE*) echo "1" ;;


SOFTWARE/OS VERSIONS

0.58.0... but the same happens using Kubuntu 14.04 (yes, from 2014)).

Steps taken to reproduce
* Open attached PDF file
* Select all text with mouse using selection tool, copy to clipboard
* Paste in text editor (Kate)
* Observed results contains additional line breaks

Alternatives investigated
* Open attached PDF file
* Select all text with "Ctrl + A", copy to clipboard
* Paste in text editor (Kate)
* Observed results contains additional line breaks

* Open attached ODT file
* Select all text with mouse using selection tool, copy to clipboard
* Paste in text editor (Kate)
* Observed results match the contents of the original file, no extra line
breaks

* Open attached ODT file
* Print to PDF
* Open resulting PDF
* Select all text with mouse using selection tool, copy to clipboard
* Paste in text editor (Kate)
* Observed results match the contents of the original file, no extra line
breaks

* Open PDF file in different PDF viewer (Chrome browser default viewer)
* Select all text with mouse using selection tool, copy to clipboard
* Paste in text editor (Kate)
* Observed results match the contents of the original file, no extra line
breaks

It is perhaps worth noting, that when selecting only a subset of the text with
the mouse tool, the phantom line breaks can be seen through the number of
characters reported selected by Okular. For instance selecting "ONE*" in the
last line reports 4 characters, but selecting "ONE*)" reports 6.

I'm not the developer, updating as part of the Okular Bug Day for the Bugsquad.
