Why are all strings ASCII-8BIT after I upgraded to Rails 3?

问题

I upgraded to RoR 3.0.1 and Ruby to 1.9.2. Now all the strings in my views are ASCII-8BIT?

I believe I have my app set up to use UTF 8

application.rb

config.encoding = "utf-8"

database.yml

development:
  adapter: mysql
  encoding: utf8

I'm running

OS X
RVM rvm 1.0.16 
Ruby ruby-1.9.2-p0
Rails 3.0.1

I'd expect that the enoding would be UTF 8 not ASCII

business.desc.encoding
# ASCII-8BIT

Since 1.9.x can concatenate strings of different encodings we see a lot of errors like this.

<p class="description"><%= truncate(business.desc, :length => 17) %></p>

The Error

incompatible character encodings: ASCII-8BIT and UTF-8

Does anyone else have this problem? Is ruby-1.9.2-p0 the correct version to use?

Thanks!

回答1:

You need to add this to every .rb file:

<% # coding: UTF-8 %>

I use the gem magic_encoding for that.

$ cd app/ 
$ magic_encoding

The default is UTF-8, but you can specify whatever you want as an argument.

回答2:

horrible issue. You need to put this at the top of each file

# coding: UTF-8

UPDATE Use the magic_encoding as described be Nerian.

Does essentially same as the below, but better.

/UPDATE

I have a rake task I don't remember where I found (kudos to that guy!) which I have slightly modified, to have this on top of each file. I've heard people say the above(what you've done) should be sufficient, but it doesn't work for me...

Anyhow, this is the rake task, just copy paste it

lib/tasks/utf8encode.rake

# coding: UTF-8

desc "Manage the encoding header of Ruby files"
task :utf8_encode_headers => :environment do
  files = Array.new
  ["*.rb", "*.rake"].each do |extension|
    files.concat(Dir[ File.join(Dir.getwd.split(/\\/), "**", extension) ])
  end

  files.each do |file|
    content = File.read(file)
    next if content[0..16] == "# coding: UTF-8\n\n" ||
            content[0..22] == "# -*- coding: utf-8 -*-"

   ["\n\n", "\n"].each do |file_end|
      content = content.gsub(/(# encoding: UTF-8#{file_end})|(# coding: UTF-8#{file_end})|(# -*- coding: UTF-8 -*-#{file_end})|(# -*- coding: utf-8 -*-#{file_end})/i, "")
    end

    new_file = File.open(file, "w")
    new_file.write("# coding: UTF-8\n\n"+content)
    new_file.close
  end
end

I'm moving from Ruby 1.8.6 and Rails 2.3.5 to Ruby 1.9.2 and Rails 3.0.3, with postregsql. In order to get this working on my project, I had to do add this to the top of any of my view templates that were being translated:

<% # coding: UTF-8 %>

The rake task provided by Ole should be easy to modify to do this as well. I didn't find his solution as given had any effect, though.
