Why does hosting swear?

Question

PHP

Why does the hosting swear at the charset=utf-8 value, but everything is fine on the local?

$dsn = "mysql:host=$host;dbname=$database; charset=utf-8";

When I remove charset=utf-8 on the hosting, everything works fine.
Hosting is free. Hostinger

We look at the PHP version on the locale and on the server + on the dock - php.net/manual/ru/ref.pdo-mysql.connection.php
