WCF REST GET - "*" in the Uri causing "400 Bad request

I have a service with the following Uri template

Services/UserPreferences/{key}

The users can specify "*" in the key. This is causing a 400 bad request. I have tried encoding - replacing * with %2A. That does not help either.

Any suggestions ?

It looks like we cannot have a "*" in the URI. Will be handling this from query parameters
