I have the following code in my .emacs when I changed to w32 last
June. So the problem might exist longer.

;;; FIXME: find out why GNU/Linux does not need this
(prefer-coding-system 'utf-8)

I just tested some Chinese files. Without that line, all of them are
being opened in latin-1 encoding and are unreadable.

Tested in GNU Emacs 23.0.91.1 (i386-mingw-nt5.1.2600) of 2009-02-26
