Emacs'support of utf-8 is still a bit mysterious to me. You might try a
few other settings:
(setq-default enable-multibyte-characters t)
(setq locale-coding-system 'utf-8)
(setq coding-category-list '(coding-category-utf-8
 coding-category-iso-8-1 coding-category-iso-8-2
 coding-category-iso-7-tight coding-category-iso-7
 coding-category-iso-7-else coding-category-iso-8-else
 coding-category-sjis coding-category-utf-16-le coding-category-utf-16-be
 coding-category-emacs-mule coding-category-raw-text coding-category-big5
 coding-category-ccl coding-category-binary))

Have you also tried to see what happened without your init file
(run "emacs -q") and then evaluating your utf-8 settings? There might be
some package you use that breaks the unicode support.

I don't know well the Windows world, but I'm sure that win98 and earlier
don't handle unicode. Of course, some apps can use utf-8, but the system
won't be able to handle this. For other OS like winME, I have no clue.
Is it even possible to copypaste unicode between ms apps ?
