Setting # encoding: utf-8 at the first line of file does help, but the strange thing is without this line UTF-8 is rejected only in subgroup! When I set conf.label = "some non-ASCII chars" it works even without this line!

config.encoding = "utf-8" is set in application.rb.

ruby 1.9.2, rails 3.0.3, AS - the latest commit from git master branch.
