Under Xournal, I add some text to a pdf file, and then I export to a pdf file. In the exported pdf file, the text I added is shown correctly, and selectable, but when I copy and paste the selected text out to a text editor, it is not the same text I added. For example, under Xournal, I add locking to a pdf file, and in the exported pdf file, when I select the text and copy and paste it into a text editor, the text is  PSGOMRK. I wonder if it is a bug of Xournal? How can I make the selected text from the exported pdf file the same as the text I added under Xournal?My OS is Ubuntu 12.04, and the version of Xournal is 0.4.5.

This seems like a fairly old bug with Xournal. I found this thread describing the exact same issue as well, titled: copy text from pdf problem (xournal). Using the latest version (0.47), I was able to reproduce the issue as well.    I then exported the annoted PDF as a new PDF and then copied the annotated string This is some extra text. and attempted to paste it in vim. Doing so I got this string: 8LMW MW WSQI I\XVE XI\X.I can continuously repeat this problem over and over. It's definitely an issue with the annotation done by Xournal. The pre-existing text, PDF 3 worked fine when I copy and pasted it.Alternative?You might want to try using Okular which can also annotate PDF files.
