Can anyone please help me to write reg expression of below. 

I want to validate a string field so it will not allow user to enter any of the below special characters

Characters   :     ~  #   @  *  +  %  {  }  <>   []  | "   \   _

here is the example something I have been using for validating phone number  :

2. phoneNoFormat = input.TFN_01.toString().replaceAll("^[0-9]{3}-[0-9]{3}-[0-9]{4}$","correct");
3. if (phoneNoFormat  !=  "correct")
4. {
5.     alert("Phone Number should be in the format of " + "<b>" + "111-111-1111");
6.     cancel submit;
7. ?

Thanks
