I've tried this on a virgin Rails 3.2.2 app. If you put the translations
for country names in the locale file using the 2 letter ISO code, it
looks something like this:
This works fine - but for Norway
I18n.t :'countries.DE' # => "Germany"
I18n.t :'countries.NO' # => "translation missing: en.countries.NO"
Case doesn't matter, the same happens with :'countries.no'.
Any idea what could be the cause for this problem?
