That seems to be the problem. I find that Netscape 4.7 on Win98 doesn't
support all the characters listed in the HTML 4.0 spec. It displays
&rho; as &rho; and &#961; as a ?.

Nor does IE 4.0. It's a little better: it treats them the same.
But it displays a little box (i.e. an unknown character thingy)
in both cases.

Nor does Opera 4.0. Same behaviour.

Amaya 2.4 does, though.

I believe that technically, this is an issue of quality of
not of conformance. Displaying a ? or a box or &rho; conforms
to the spec, I believe... yes; see:
	"5.4 Undisplayable characters"

You don't need any <META> stuff; you're supposed to be able to just

but the implementations don't grok.

There's a nasty hack involving <font face="symbol">...</font>
and such, but if you want to do that sort of thing, I'll let
you figure it out. But I will provide a clue:
