Just a typo; someone did a search-and-replace and inadvertently
modified this. (They were trying to s/UTF8/UTF-8/ in the text, but not
in property names.)

The way this is supposed to be handled is the _NET_SUPPORTING_WM_CHECK
property; you have to monitor the window stored in
_NET_SUPPORTING_WM_CHECK, and use _NET_SUPPORTED only if that window
is still alive.
