Make sure you use InnoDB and UTF-8 when creating tables through migrations

If you want to pass specific options like the table type and the charset to use when creating tabled though Rails migrations, pass an options parameter to the create_table method:

create_table :my_table, ptions => 'ENGINE=InnoDB DEFAULT CHARSET=utf8', :force => true do |t|
t.column :column1, :string
t.column :column2, :string
end
