get method with chinese character

Dear ASP experts,

i'm trying to do a dictionary search, I'm using a get variable and retrieving the result with request.querystring, If I pass an english word it works fine, but if I pass a chinese character it returns question mark(?):

Eg 1.
http://www.test.com/testpage.asp?word=tree
the word value is tree

Eg2.
http://www.test.com/testpage.asp?word=l
(I put chinese character "gong1")
the word value is ?

my codepage=65001and Response.CharSet = "utf-8".

Thanks in advance,

<% @ codepage=65001 %>
<%
Response.CharSet = "utf-8"
'testpage.asp
response.expires=-1
getword = request.querystring("word")
response.write getword
 
%>
