I need to do a query on a long text area field that contains special characters, "-" "(" ")".  I found an escape map that seems to have come from the Salesforce Developer site, but it won't save.  Can someone help me figure out how to fix it?  I changed all of the double quotes to single quotes and that didn't work.
Thanks
