How to restrict entering special characters in a Project name field?

Hi All,

Is it possible to restrict the user from entering some special characters in a field? by using page composer -> EL

For instance, on the Project Creation page, Project Name and Project Number field should be restricted from entering special characters?

I have tried the below but didnt worked:

#{bindings.ProjectName.inputValue.contains('$')}

#{bindings.ProjectName.inputValue.matches("$(.*)")}

Also tried creating a field rule in Application Composer.

Navigation -> Projects ->Project Financial Management -> Create.

Thanks,
