Does anyone know of a list of LaTeX fonts that can be considered as already available on typical platforms? My interpretation of "typical platform" now means Windows XP, Vista, 7, whatever the current crop of Mac OSes are and, possibly not very likely, Ubuntu.
I know there are other platforms (I've had quite a few Linux distributions around the house), but in my case the above matches the platforms readers of my non-math LaTeX documents would have.
Of course, I am aware of the Font Catalogue, but my question is looking for the "safe subset" which I could use without my readers having problems and needing to install fonts. To be precise, I'm producing PDFs. Ignoring Ubuntu, it's quite possible that most readers will also have MS Office installed (which comes with a number of fonts) but I cannot guarantee it, so to play it safe, I cannot fully rely on it.
I did google for this, but couldn't find such a list, perhaps others know more.
Thanks in advance.
