Not a bug XF does not allow config.php to define charset!

Code: 
$db = Zend_Db::factory($dbConfig->adapter,
    array(
        'host' => $dbConfig->host,
        'port' => $dbConfig->port,
        'username' => $dbConfig->username,
        'password' => $dbConfig->password,
        'dbname' => $dbConfig->dbname,
        'adapterNamespace' => $dbConfig->adapterNamespace,
        'charset' => 'utf8'
    )
);

This code, hard-codes the charset of the database connection to utf8. So if I were to put into my config.php the following, it would be ignored:

Code: 
$config['db']['charset'] = 'utf8mb4';

My recommendation is to set utf8 as the default, and allow us to define a custom charset for the connection.
 
This is really as designed and there are further changes that would need to be made to do what you want.
