Avoidance of special characters in database names when database is created
Disallowing using special characters (period, minus, backtick) in database names when database is created. This would reduce database errors caused by database names in wrong format.
The database server defines, what a wrong identifier format is, and for MariaDB for example, dashes and periods are allowed https://mariadb.com/kb/en/identifier-names/ . Backticks are already exluded in the Plesk GUI from database names, but at the moment there is no reason to limit the name more than what the database server allows. An artificially imposed limit will for sure trigger requests by other users to allow at least all the characters that the database server allows. For that reason, this feature request must be declined.
