You can use regular expressions in JavaScript to check a respondent's answer for any of the above characters. For example, if you want to display an error every time a special character is entered you could use some custom JavaScript verification such as

var answer = SSI_GetValue("QuestionName");

if (answer.match(/[;,\/\\]/)) {

  strErrorMessage="Please revise your answer";

}
