Forum:Interwiki link not working with question marks?

Trying to use the usual method to link to a page in the Forum: namespace on Wookieepedia didn't work properly. See this diff. The earlier version made an interwiki link which took me to "Forum:SH: Mobile Version", but the correct title was "Forum:SH: Mobile Version?". Could this be because the page I tried to link to contained a question mark on the end? &mdash;Silly Dan (talk) 21:26, 31 March 2009 (UTC)
 * From personal experience, I would have to say yes, it's the question mark. However, I think that the staff can provide a better answer. --Michaeldsuarez (Talk) (Deeds) 23:05, 31 March 2009 (UTC)


 * Odd. The question mark is encoded (%3F) by the browser in the first request, but the redirect returns it unencoded, so the browser sends it as is and the server interpret it as a query string, not as part of the title. I don't know if this could be exploitable somewhat:
