ytsearch fails when it encounters en-dash

[breadcat]

I'm running:

youtube-dl -x --audio-format=mp3 "ytsearch:Styx – Half-Penny, Two-Penny A.D." --verbose

Which gives me:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 5: ordinal not in range(128)

If I replace the en-dash (\u2013) with a normal dash (-), it searched and proceeds perfectly.
I'm picking up the en-dash character from a 'now playing' section of a radio stations web page.

This issue will be fixed in the next version. Thanks for the report.
