javascript - Accessing Json fields with weird characters

i have a json string im converting to object with a simple eval(string);

heres the sample of the json string:
var json = @'
"{ description" : { "#cdata-section" : "<some html here>" } }
';
var item = eval('('+json+')');

I am trying to access it like so

item.description.#cdata-section

my problem is that javascript does not like the # in the field name.. is there a way to access it?
