sending a £ symbol via IE to Twitter via ?status=xyz (unicode error)

Got a link that allows a user to share a message to their twitter followers. The URL contains a £ sound which twitter complains about when clicked from IE but works fine in FireFox.

Any advise please?

Thanks

The pound sign must be URL encoded, all non-ASCII and even some ASCII characters have to be encoded in order to be passed via the GET protocol (or a URL).

the pound sign is %C2%A3
