Strange signs while preview articles

Destroyerror

Hello guys, have some problem, need you help, so - after I copy spinned article from "the best spinner", and then preview it - there are some words like "can don’t"  or "other user’s snap". If you have the same problem or know solution plz tell me, I dont now or this because of best spinner, or some punctuation marks or just GSA preview bug. Wait you answers.

I think this is from char spinning. Did you make use of that?
