Character encoding issue during local media scan

[rmccawl]

When running mopidy local scan on a clean mopidy install I get the following error message

INFO     Scanned 3500 of 5494 files in 25s, ~14s left.
ERROR    'ascii' codec can't encode character u'\ufeff' in position 0: ordinal not in range(128)

I am running mopidy on OSX, installed via homebrew.

I had another look at the error message, it appears the character it can't encode is u'\ufeff' which is the Byte Order Mark character - http://stackoverflow.com/a/6786646

Something in my library must have this in a filename or tags.
