MySQL AbstractSchemaManager::createDatabase missing charset and collation

[fredw]

I need to create a new database on MySQL, but the AbstractSchemaManager doesn't respect my ORM entity manager charset param:

$em = Doctrine\ORM\EntityManager::create(
    [
        'driver' => 'pdo_mysql',
        'host' => getenv('DATABASE_HOST'),
        'port' => getenv('DATABASE_PORT'),
        'user' => getenv('DATABASE_USER'),
        'password' => getenv('DATABASE_PASSWORD'),
        'dbname' => getenv('DATABASE_DATABASE'),
        'charset' => 'utf8',
    ],
    $config
);
$params = $em->getConnection()->getParams();
$connection = DriverManager::getConnection($params);
$connection->getSchemaManager()->createDatabase($params['dbname']);

I took a look at the sources and I saw that there isn't parameter on this AbstractSchemaManager::createDatabase:
https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Schema/AbstractSchemaManager.php#L428
And consequently on MySqlPlatform::getCreateDatabaseSQL there isn't a parameter to inform the charset and collection:
https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Platforms/MySqlPlatform.php#L384

I don't have a very thorough knowledge of doctrine\dbal, but wouldn't be ideal be a way to specify the charset and collation following the MySQL create database standards?

CREATE DATABASE mydb
   DEFAULT CHARACTER SET utf8
   DEFAULT COLLATE utf8_general_ci;
