1. Access the object or the employee where you have this field.
2. Add a text in the first line.
3. Add another text in the second line with the special character that should trigger the rule.
4. See that the error message was not triggered. 

For a text box field the regular expression consider only the first text line but to consider all the text add "(?)" in your regular expression.

Please see the comparation below:

1. For a single text like the regular expression will be:  .*[!,@,#,$,%,^,&,*,(,),_,+,=,{,},",?,\,;,:,<,>].* (for more details on this, please refer to KBA 2691521);
2. For a text box, add the expression (?) like in regular expression: (?s).*[!,@,#,$,%,^,|,&,*,(,),_,+,=,{,},",?,\,;,:,<,>].*
