the two slashed o's in cmr are norwegian letters -- text only.
the \emptyset provided by knuth (in cmsy) is a slashed zero --
this is shaped.
the variant emptyset in the ams fonts (which the ams prefers)
is a slashed circle -- geometric.
the latter two are both used; which one i think is almost always
a matter of house style.
