UnicodeDecodeError: 'ascii' codec can't decode byte

When using a special character in the author field for a behavior it crashes during execution. I am pretty sure this used to work.

Here is the output:

[ERROR] [1616671138.416851, 814.633000] [/behavior_launcher] [rosout]: bad callback: <bound method BehaviorLauncher._callback of <flexbe_widget.behavior_launcher.BehaviorLauncher object at 0x7f2af85ddc10>>
