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

Question

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 fol

Answer 1

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.

Answer 2

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
