Is there a method to restrict the use of special characters other than "space, (), [], and "

Question

Hello, 
 
 Is there a method to restrict the use of special characters other than "space, (), [], and <>" in the text field or paragraph field? 
 Kind of thinking using validation. 
 
 Thank you.

There are many ways of doing it One of the methods that I use the most is to see Stripwith() function to remove all the special characters and then compare the length of the two strings. Also, isolate this in a rule so you can add or remove characters in the future with ease.
