Seems like it's a normal behavior for pdf, when I create a pdf with text, I split text after a whitespace and put it into a pdf file. After saving that space is replaced with paragraph symbol. 

Okay, I think It is not a okular bug. Thanks.

This is the text entity reordering problem. Okular just takes an unordered set of visible characters with position, and then arranges them to a string as it feels appropriate. Space characters are indeed lost in this process.
