js.coffee.erb 由于从数据库获取 å æ ø 字符而引发错误

Question

Env: Rails 3.2.11 app

资产/javascript

我有这个文件home.js.coffee.erb:

jQuery ($) ->
  $.supersized
    # Functionality
    slide_interval: 3000 # Length between transitions
    transition: 3 # 0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left
    transition_speed: 700 # Speed of transition
    thumbnail_navigation: 0
    # Components                            
    slide_links: "blank" # Individual links for each slide (Options: false, 'num', 'name', 'blank')
    slides: [
<% for cs in CreativeService.where('active') %>
      image: "<%= cs.featured_image.url %>"
      title: "<%= cs.art.name %> > <%= cs.title %> by <%= cs.artist.first_name %> <%= cs.artist.last_name[0]  %>"
      thumb: "<%= cs.featured_image.url(:small) %>"
      url: "/creative_services/<%= cs.id %>"
    ,
<% end %>
    ]

这在我的开发环境中是正确的，但是一旦部署到HEROKU，我就会得到这个错误

throw Error("Encoding::InvalidByteSequenceError: "\xC3" on US-ASCIIn  (in /app/app/assets/javascripts/home.js.coffee.erb)")

这个错误似乎是由于从数据库中获取的字符(我使用挪威语)

& lt; % = cs。title %> <=我能对这个字符串做些什么来防止这个错误?

在我的Gemfile:

group :assets do
  gem 'sass-rails', "~> 3.2.5"
  gem 'uglifier', '>= 1.0.3'
end
gem 'coffee-rails', "~> 3.2.2"     <= outside or inside the group doesn't help

我试过在应用程序中添加这些。

Encoding.default_external = Encoding::UTF_8
Encoding.default_internal = Encoding::UTF_8

也在js.coffee.erb文件的开头添加这个，仍然没有成功:

# encoding: utf-8

去年发现:

我认为错误是因为从数据库中获取的文本而发生的。

Try

heroku config:set LC_CTYPE=en_US.UTF-8
