parameter passiinf in URL....

Hi my friends,
I have a form that opens up a new window when the submit button is clicked.
Form results are then passed to the new window throuh URL.

My problem is that I am working with double-byte characters (Japanese).
When I enter single-byte (English) input into the form, the script works
normally.However, when I enter double-byte (Japanese) characters, and
access the the URL value passed to the new form( using
<%=request.getParameter("myFieldvalue")%> ),the double byte charactors appear to be junk.

Any hints would be greatly appreciated
