Title: [Twig templates] used HTML5 meta charset tag and removed hardcoded ones

I'd also have a suggestion, shouldn't the framework forbid twig to have a different charset than the kernel? Currently it's only the default value : https://github.com/symfony/symfony/blob/master/src/Symfony/Bundle/TwigBundle/DependencyInjection/Configuration.php#L124
