If I remember the discussions around charsets in URIs correctly,  
utf-8 is recommended by the w3c, but not required by the URI spec. So  
there can be other encodings and there may be applications for uri  
templates in that context. What I am trying to say is that conversion  
of %-endoding back to characters is not well defined.
