big5 renderURL code

[kevnlin]

I try it

http://1.1.1.1/portal/portal/default/??


in jsp file
out.println("<a id=\"adminPanel\" href=\"" + (renderResponse.createRenderURL()).toString() + "\">"+ "ttest adminurl" + "");

show
/portal/auth/index.html?ctrl:cmd=render&ctrl:window=default.%E6%B8%85%E6%96%87.444 ttest adminurl

why the big5 word change to default.%E6%B8%85%E6%96%87.444


when I click URL and show error page
