postfinance doesnt accept generated qr-code
Hi, our postfinance doesnt accept our generated qr-code because there are characters in line 30 that are not allowed (extra_infos, '##' character for visual line split). Is it possible to remove the character after line split (line 680 in bill.py)? Currently its readded after line split.
