我正在撰写丹麦网络应用，并尝试验证电子邮件地址。这些可以包括人物æøå等。这是我的rspec代码：
User.create(@attr.merge(:email => 'æøå@bætter.nåw.ørg'.to_s)).should be_valid
我在User.rb中的验证：
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, :presence => true, :format => { :with => email_regex, :message => 'must be valid email' }, :uniqueness => true
这完全搞砸了rspec / autotest，它在这个堆栈跟踪中失败了很多：

也许将它添加到测试文件的顶部（具有特殊字符的文件）：
