Description

Hello, I'm a core member of the @faker-js/faker library.
We already use many of your validation methods to verify the integrity of our generated fake values.

For our newest addition, we want to verify codes for the representation of the names of scripts. Those are standardized by ISO-15924.

Suggested Validation
