fix UnicodeDecodeError on Windows

[chedidelias]

This fixed it on my computer. However I would need someone to confirm it doesn't break anything on mac :)

Thanks for the PR! The docstring says:

The default encoding is platform dependent,

so that seems to explain the problem, and I'm quite sure there'll be no regressions on other platforms.

However, you passed in the kwarg as -encoding instead of encoding that the function signature calls for. If you fix that and Travis passes, I'll merge the PR.

Removed it, sorry for the typo!
