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

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

   production:

4. Run rake figaro:heroku

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