Ordering on Heroku and special characters (å ä ö)

Hi!

I just pushed an app to Heroku for the first time. I notice that the
ordering is not quite correct. It is on my local machine though.
The issue is that the swedish characters and are ordered like A A and
O. I guess this is because some collation or locale is wrong.

Any ideas on how to fix this on Heroku?
