x-clipboard-yank doesn't decode utf-8 string

[Zhang Wei]

The following line has been put in my .emacs:

  (setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING)

When I select some text from Mozilla-firefox using left mouse
button, but without issuing cut/copy command explicitly, then I paste
in emacs with middle mouse button or C-y, everything is OK,
which means the X PRIMARY selection method works fine.

But if I issue cut/copy command explicitly after
selection (select Edit/copy from Mozilla-firefox's menu, or C-c),
and then paste in emacs using Edit/paste menu item, what I got is
undecoded utf string, something like this "\u60a8\u4e0a\u6b21",
it seems that the X CLIPBOARD selection method does not work.

The following patch could fix this problem, but I'm not sure if
it is the best way.
