I called typestream.unarchive_from_data on a "attributedBody" string from a MacOS messages .db file. The above error is thrown. I'm unfamiliar with context variables so the fix could be very simple, but I'm unsure where to begin. Working in Python 3.9.

This looks like a bug in my code - thank you for the report! I can't promise when I'll get around to fixing it and making a new release though.

The error here comes from calling str(obj) or print(obj) on an object returned from typestream.unarchive_from_data. As a workaround for now, you can instead use print(repr(obj)) or print("\n".join(as_multiline_string(obj))) (the second one requires from typedstream.advanced_repr import as_multiline_string).
