咖啡编码：：未定义转换错误，从ASCII-8位到UTF-8位

Question

如何繁殖

Gemfile

gem 'haml'
gem 'sass'
gem 'coffee-script'

app/app.rb

get '/javascripts/rus_test.js' do
  content_type 'text/javascript', charset: 'utf-8'
  coffee :"../../public/javascripts/rus_test"
end

public/javascripts/rus_test.coffee (工作)

alert 'Hello World!'

localhost:3000/javascripts/rus_test.js

(function() {

  alert('Hello World!');

}).call(this);

public/javascripts/rus_test.coffee (不工作)

alert 'Привет!'

给出误差

编码:从ASCII-8位到UTF-8位的未定义转换错误at /javascripts/rustest.js "\xD0“

我尝试在config/boot.rb.中设置Encoding.default的几个变体

启动初始化的变体之一

Padrino.before_load do
  Encoding.default_internal = nil
  # Encoding.default_external = 'ASCII-8BIT'
end

它适用于带有俄语文本的HAML，但不适用于SASS和咖啡

我该怎么做才能修好它？

Answer 1

删除可笑的Encoding.default_internal = nil并将此代码添加到猴子补丁Tilt中：

# this makes tilt to treat templates as properly encoded (respect Encoding.default_external)
module Tilt
  class CoffeeScriptTemplate
    def prepare
      @data.force_encoding Encoding.default_external
      if !options.key?(:bare) and !options.key?(:no_wrap)
        options[:bare] = self.class.default_bare
      end
    end
  end
end
