Heroku and Rails: how to set utf-8 as the default encoding

Today, I created a copy of a working app, which runs perfectly on Heroku, and tried to deploy it on Heroku as a starting point for a new project.

I added the new folder as a git repository, created a new remote repository on GitHub, edited the config file and gave new names to the databases, created the new databases and tried to deploy on Heroku.

Now the app crashed on startup because Heroku finds some utf-8 text inside my source files and doesn't recognize them:

2011-06-27T14:23:10+00:00 app[web.1]: /app/app/controllers/home_controller.rb:118: invalid multibyte char (US-ASCII)
2011-06-27T14:23:10+00:00 app[web.1]: /app/app/controllers/home_controller.rb:118: syntax error, unexpected $end, expecting '}'
2011-06-27T14:23:10+00:00 app[web.1]: ...tue azioni, conquista la città!"}

How can I tell Rails and Heroku that all of my source file are utf-8 encoded? Should I add a UTF-8 BOM in EVERY file? That's crazy and I was not doing so in my previous app that worked beautifully.

I'm using Rails 2.3.6.

I found this, much easier solution:

Just add ENV['RUBYOPT'] = "-Ku" to your environment variables on Heroku. You can do this with figaro gem:

  1. Add gem "figaro" to your Gemfile
  2. bundle install

  3. Insert this code in config/application.yml:

    production:
  RUBYOPT: "-Ku"

  4. Run rake figaro:heroku

Also, you can try with magic_encoding gem, but I dislike this approach.

In your config/application.rb, 

  config.encoding = "utf-8"

in the database.yml,

 development:
     adapter:  mysql2(whatever your db)
     host:     localhost
     encoding: utf8

you also have to add(including the hash)

# encoding: UTF-8
