Ordering on Heroku and special characters (å ä ö)


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 Å Ä and Ö 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?
