Proper behavior per EWMH is for the window manager to set
_NET_WM_VISIBLE_NAME, probably in the manageHook but possibly in
handleEventHook, and then to use that when it exists instead of _NET_WM_NAME
or WM_NAME.

That said, Decoration is certainly able to do it, although it doesn't come
with a "canned" configuration that does so.  You would override the
"decorate" method.  With SimpleDecoration I'd (after using a handleEventHook
to set _NET_WM_VISIBLE_NAME as above) change it to use a modified getName
(which it currently gets from XMonad.Util.NamedWindows) that knows about
_NET_WM_VISIBLE_NAME.
