[pjones]

I have no idea why US-ASCII is being used on line 117.

I'm happy to merge a fix once someone figures this out.

Got it working by setting the following env variable:

export RUBYOPT="-KU -E utf-8:utf-8"

I also set $LANGUAGE and $LC_ALL to $LANG (de_DE.UTF-8 for me) as these were not set, not sure if that was required.
