Rails 3.1无效的多字节字符（UTF-8）

Question

我正试图通过这个简单的断言

assert_select '.price', /\€[,\d]+\.\d\d/

在视图中，.price类的代码是

<span class="price">
 <%= number_to_currency(product.price, options = {:format => "%u%n", :unit => "&euro;"}) %> </span>

当我使用默认的<%= number_to_currency(product.price) %>时，一切都很好。当我切换到欧元时它就不会工作了。

这是错误消息：

/Users/noapologize/.rvm/gems/ruby-1.9.2-p290/gems/activesupport-3.1.0.rc4/lib/active_support/dependencies.rb:237:in `require': /Users/noapologize/rails_projects/depot/test/functional/store_controller_test.rb:11: invalid multibyte char (UTF-8) (SyntaxError)
/Users/noapologize/rails_projects/depot/test/functional/store_controller_test.rb:11: invalid multibyte char (UTF-8)
/Users/noapologize/rails_projects/depot/test/functional/store_controller_test.rb:11: syntax error, unexpected $end, expecting keyword_end
    assert_select '.price', /\€[,\d]+\.\d\d/

我想我写这个assert_select的方式是错误的。有人可以启发我吗？

感谢您的时间。

如果从欧元符号中删除转义斜杠，则此正则表达式将正确编译并正常工作。
