Hi,
you can make use of Regex expressions(System.Text.RegularExpressions.Regex). Have a look at an example shown in an old post.
community.dynamics.com/.../171654
additionally if you will search about regex expressions, you can find lot of material on it.
Define all special characters in a list. Use strContains function by iterating through the list.

If you need to know more about regular expressions, you can learn on this site: http://regexr.com/
