When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Glottopedia",
   title = "Empty operator --- Glottopedia{,} ",
   year = "2009",
   url = "\url{http://glottopedia.org/index.php?title=Empty_operator&oldid=7603}",
   note = "[Online; accessed 28-January-2026]"
 }
