UnicodeEncodeError in raygun4py

As you can see in the stacktrace below, Raygun failed to process an error because of a UnicodeEncodeError in raygunmsgs.py. As a result, I have no idea what the underlying error was (Raygun lost it).

I have two asks:

• Can you all fix what seems to be a bug in your Python library?
• Can you have your Python library log the error before trying to send it to your servers? (So that in case there is an issue on your end, developers can still debug)

Thank you!
