Cannot use newline in attribution

[La-S]

Hi,

Thank you for making this library. Would it be possible that you could add a way to make newlines in the attribution work? I have a problem where my attributions aren't small enough to fit on one line, and would greatly appreciate the ability to add more than one line to the attribution section. When I try to add \n to my attribution, a ? character appears, instead of a newline.

Thanks, Lance
