Code viewer example crashes

[aitoehigie]

Hello folks,
Whenever I try to run the code viewer example, it crashes when I scroll directories and returns this traceback:

UnicodeEncodeError: 'utf-8' codec can't encode characters in position 4340-4342: surrogates not allowed
*** You may need to add PYTHONIOENCODING=utf-8 to your environment ***

I tried setting that environmental variable in my shell but it still keeps crashing.

Any idea on how to fix this?

Thanks
