Hi,
I am not 100% sure, but "fc-list" and friends might not always list the fonts
even if they are on the user's system. For example, on my gentoo linux desktop,
fonts for Adobe Acrobat are installed in a specific directory and are not
included in the system-wide fonts by default. In fact, I have had to copy some
of the Adobe fonts to my $HOME/.fonts to do some testing.
The (more dificult) solution could be to make a shell script which will run the
compilation of the xelatex source and detect whether or not the run was
succesfull - if not, change the input file to the other font and retry.
Regards,
Wilfred
