Unicode crash on exporting to CSV

Surrogates again... I had a similar problem with #170, but xml.etree fixed it by itself. I should probably just remove these characters from exported paths, or something like that...

[ghost]

So yeah, I can reproduce the issue by manually (through a python os.rename()) creating a buggy filename, scanning them and then trying to export the CSV. As with #170, I should just clean those buggy characters out.

... or, just use errors='replace' during the encoding phase...

[ghost]

Oh well, it's more complicated than that after all...
