Application Composer: Validation/Trigger Rules Not Restricting Special Characters in Project Name

Summary:
We are using Application Composer to configure business rules and triggers within our instance. Specifically, we want to restrict the entry of special characters in the “Project Name” field (e.g., !@#$%^&*()). Despite creating both validation rules and triggers to block these characters, users are still able to save project records with special characters.

Content (please ensure you mask any confidential information):

Created “Validation Rules” using regular expressions (e.g., ^[a-zA-Z0-9 ]*$) within Application Composer for the Project Name field.
