20750	Explain *  and ∅ in Layer info window	Klumbumbus	team	"The new characters from #12326 should have an explanation. (While * is well-known, ∅ not so much I think.)
I made a patch, please review. It creates no additional i18n string and changes the term ""document"" to ""layer"". ""document"" was a bit strange.
