I'm trying to pass information from a form on a client's website to WorldPay via a redirect query string. I have everything set up and it seems to work except that when I set up the query string as set out by WorldPay in their documentation (http://www.worldpay.com/support/kb/bg/htmlredirect/rhtml.html), the mandatory '¤cy' part of the url query string is being changed to '¤cy' upon saving the confirmation. None of the other parts of the string are being mangled in this way, and it doesn't matter where I place '¤cy' in the string, it ends up the same way.
Obviously, upon submission, WorldPay rejects the submitted redirect with an error. This is now driving me insane, so any leads to fixing this would be much appreciated. Thank you.
