Fix rails database collations

Today I discovered my Ruby on Rails development environment database migrated with the wrong character encoding. It was using the MySQL default encoding latin1.
I didn’t feel throwing my database away because it contains a lot of stuff.

I used the following snippet to convert all columns to utf8

    ActiveRecord::Base.connection.tables.each do |table|
      ActiveRecord::Base.connection.execute( "ALTER TABLE `#{table}` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci")
