Allows to configure locale fallbacks through config.i18n.fallbacks. The default setting
config.i18n.fallbacks = true in production.rb will make I18n.t lookup fallback to the
I18n.default_locale if a translation could not be found for the current or given locale.
config.fallbacks = true
config.fallbacks.map = { :ca => :es }
config.fallbacks.defaults = [:'es-ES', :es]
config.fallbacks = [:'es-ES', :es]
config.fallbacks = { :ca => :es }
config.fallbacks = [:'es-ES', :es, { :ca => :es }]
