Yes, I would, because the _search string_ (i.e. the string supplied by
the user to search for) was just "e", not a regexp.

The fact that "è", "ĕ" or "ⓔ" can be matches in this case is due to
the combination of (a) the search string, _plus_ (b) the current
Isearch options (char-fold enabled in this case).

So, the header line of *Occur* buffers could perhaps show, in addition
to the search string, some Isearch options -- like the Isearch prompt
string does.  But showing that huge, auto-generated regexp in place of
the original search string makes little sense, IMO.
