I have a group of radio buttons with their values set to specific expressions - each one with a PI symbol. There is a value stored in a cookie with one of the expressions within the radio buttons' values. If I grab the value from the cookie to compare with the selected values from the radio buttons I get π in place of the PI symbol for the answer from the cookie and from the values from the radio buttons I get the actual symbol (i.e. N). How can I easily compare the value from within the cookie with the HTML equivalent on the page? Any help would be most appreciated.
