We need to escape quotation marks, but can we use utf8 (?) for the rest?

In the past this helped me:

Would be good to know where the encoding gets messed up. MongoDB uses UTF-8 already per default, but I would assume it can happen after we query the database.
I have a class for solving these problems in graphler, i can simply copy the code and put it in front of everything we retrieve from the db if the error is there.
