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.

Hi Vinay,

You can solve it with coding. You can call Regular Expressions. How to use this can be found in an example: WinAPI::isFileNameValid OR SysEmailDistributor::validateEmail

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