title: define character in rails migration
body: <p>All tables and fields created with Rails migrations have <code>latin1_swedish_ci</code> collate.
  Because my project use russian language, this collation is improper.</p>
  
  <p>Is it possible to use migrations with <code>utf8_general_ci</code>?</p>
  
  <p>P.S. My database.yml:</p>
  
  <pre><code>development:
    adapter: mysql2
    encoding: utf8
    collation: utf8_general_ci
    reconnect: false
    database: my_development
    pool: 5
    username: username
    password: 'heavy'
    host: localhost
  </code></pre>
