I have a form which would be posted from chinse pocketIE(pocket pc 2002) to servlet. There is a field (e.g. "TextField") in the form which is going to accept chinese characters input.

My problem is that when I call request.getParameter("TextField") I got "??" no matter the content type of the form is "Big5", "UTF-8" or "ISO-8859-1". And I have no way to convert "??" into other charset which gives meaningful characters.

However, it is no problem when I posted the form from IE6.

Any solution ?
