Update of /sources/public/html5/websockets
In directory hutz:/tmp/cvs-serv22686

Modified Files:
	Overview.html 
Log Message:
Make WebSocket silently convert isolated surrogated to U+FFFD rather than throwing an exception. This will result in data corruption when a user types in astral-plane characters that get truncated by naiive script half-way through, rather than crashing the application. (whatwg r7084)
