Yii2 Как сохранить кириллицу в базе?

$tableOptions = null;
if ($this->db->driverName === 'mysql') {
            // http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci
     $tableOptions = 'CHARACTER SET utf8 COLLATE utf8_unicode_ci';
}
$this->createTable(
		'tablename', 
		[
			'id' => $this->primaryKey(),
			//
		], 
		$tableOptions
	);
