UrlEncode - UrlDecode problem: not symmetric

[lookaround]

Hi,
I have a problem with UrlEncoding/UrlDecoding.

I have two chars (�京);
the HTTPUtility.UrlEncode writes in the html the text:
%e6%9d%b1%e4%ba%ac

The Request.Querystring.ToString() of the called page returns:
%u00e6%u009d%u00b1%u00e4%u00ba%u00ac

and after having UrlDecoded I obtain the text
�京

I don't know what's the problem... How should I do to obtain the
original text using UrlEncode and Decode?
I've posted the problem on asp.net forums too but didn't finad any
solution...
Thank you very much in advance for any idea!

It is symmetric.

Response.Write(
System.Web.HttpUtility.UrlDecode(
System.Web.HttpUtility.UrlEncode(
"�京")));

Output: �京

It looks like you encode or decode the string more than one time
