[XeTeX] default fonts for text and math in xelatex (ubuntu, texlive 2011)

[peter knezel]

Hello Ross,

thanks for the explanation - it is much clearer now.

I am able to list all fonts on ubuntu with *fc-list* command.
How should I know which of them supports math fonts and which of them is
monospaced (like Courier New)?

Regards,

Peter
