David, Thx for the response. I'll follow up on and both the direct font approach and the MathML approach. I noticed that in http://www.w3.org/TR/2003/REC-MathML2-20031021/chapter2.html#fund.examples you use images instead of a MathML renderer. Why did you make that choice? I think our situations are similar since we are both publishing W3C specs. One consideration is that the spec must be easily viewed. Do you consider that prerequing a MathML renderer poses an unacceptable requirement for W3C specs? Do you have an example of a W3C spec that uses a MathML renderer?

You could of course use MathML, which doesn't entirely free you from worrying about installed fonts but does provide a more robust way to access mathematical typographic requirements. Although simple cases you may be able to get by with just accessing the foints and using textual markup using mathml rendering, which is built in to mozilla/netscape and freely available as a a behaviour extension for IE (MathPlayer from Design Science). You could then access Z as <mi>ℤ</mi> or <mi mathvariant="double-struck">Z</mi> > Are there any fonts available to render this and other math symbols > defined in Unicode?

Can I specify some fonts so > that all symbols get rendered in both browsers? the TeX, Wolfram, and Design Science Math fonts are all usable by mozilla's MathML renderer, see http://www.mozilla.org/projects/mathml/fonts/ Note that these fonts are not naturally unicode encoded so you have to use mathml markup to access them and mozilla's mathml engine maintains tables that map the unicode slots to font positions for these specific "known" math fonts.
