Problem with encoding (Greek characters challenge)

[iamedu]

First of all.. what's important.. I'm very excited to see vimgolf, it's a great piece of software and a lot of fun!!

I was trying to solve the Greek character challenge but I noticed that I get strange characters in the output, you can see in the image.

I've tried to solve it for a while.. and I'm still think it might be my machine's encoding.

If it's of any help the generated vimgolf files are over here: http://db.tt/Dz1cS7Dp

Thanks for everything and keep up the good work!

The hint from @jdelkins about ruby 1.9 helped me find the problem. The reason this bug shows up in ruby 1.9.3 is that it defaults to psych, which parses YAML's \x80 and higher hex escapes in a different way than syck, interepreting each one as a UTF-8 character instead of a byte.
