No. (But it doesn't any harm either.)
There are lots of other problems (apart from the question,
whether fc-list is the correct test):
* \write18 might be disabled, then the write line isn't executed.
At least this can be tested by \pdfshellescape
(0 is disabled, 1 is unrestricted enabled, 2 is restricted enabled)
* \write18 can be enabled, but restricted (\pdfshellescape is 2).
The command might not be part of the allowed program list.
There is no way to test it except trying the feature.
* fontcheck.tex is generated in the current directory.
However it can be read from a different directory, depending
on the TeX configuration (TEXINPUTS, ...).
Especially problematic if \write18 is not enabled and the
existence of the file is used as check, whether the \write18
line has worked.
This can be cured by the pipe feature:
\openin\fontcheck |fc-list 'Myriad Pro'
Does it (especially the single quotes) work in Windows?
* A first line is also read, if the file is empty.
The macro that stores the line contains the character,
configured by \endlinechar and is empty if \endlinechar=-1.

Re: [XeTeX] Checking if a font exists
You can edit the file fonts.conf (for example in /etc/fonts or /usr/X11/lib/X11/fontconfig) or ~/.fonts.conf, your personal copy that fonts are searched additionally in particular places. Certainly, but on a standard system this may not be set. Thus testing in fc-list would return a negative, even if the font is installed (and with the proper settings in fontspec, available to xelatex). But I subscribe to Martin's statement: let xelatex report which fonts it knows, rather than an auxiliary program.

Rather than testing for several fonts on a user's machine, and picking the best match, like if the content were styled via (X)HTML+CSS, with a font rule that specifies various fonts with fallbals, part of the power of TeX is the fact that it will always look the same on any machine it's compiled on, provided the dependencies are met. So, either your document will look the same no matter what machine it's compiled on, or it doesn't compile.

Re: [XeTeX] Checking if a font exists
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.

Wilfred

Some variation of

\newread\fontcheck

\ifeof

in your main TeX file. (I tested only the first

and of course test the font names listed in that file
in any way you

(Note I'm a Linux (Ubuntu) user and know not much

Anyway, thank you Barry MacKichan for the tip: I asked
the same
question on this list some months (years?) ago and the
aswers were
rather unsatisfactory.
*This* looks it could work.

Hi Alan,
Is there a way to check whether a font
is present in a user's
system? I need to generate a
document with Myriad Pro if it exists,
Arial otherwise, and if neither, exit
with an error.
Myriad Pro is nothing like Arial,
though... but just to make your
life worse: thought about version numbers?
There are many versions of
Myriad Pro, and many versions of Arial.
How do you know which version
numbers are permissible?
Well, since I have no information on that,
I'll assume that all are
useable.
But let's step back for a moment because
there's a fundamental
problem with your question: if you're
using TeX, you're implicitly
saying you care deeply about the
typesetting of your document, which
includes being particular about which
stretches of text use what
font. Not just which various fonts look
good for this text, but
which font is the one I intend to use for
this bit of my document.
Rather than testing for several fonts on a
user's machine, and
picking the best match, like if the
content were styled via
(X)HTML+CSS, with a font rule that
specifies various fonts with
fallbals, part of the power of TeX is the
fact that it will always
look the same on any machine it's compiled
on, provided the
dependencies are met. So, either your
document will look the same no
matter what machine it's compiled on, or
it doesn't compile. The idea
that it will compile with Myriad Pro on
one machine, and Arial on
another, basically violates the very idea
of TeX.
Sure, in an ideal world. But this
particular application is to
conform to standards set by my university, and
for better or for
worse, they've allowed Arial to substitute for
Myriad Pro if the
latter is not available. And it may turn out
that since I can
reasonably assume that Myriad Pro should be
available, I can fix
things so that it is the only font used, as
long as it can be found.
The better way to solve whatever problem
you're having that made you
wonder how to detect certain fonts is to
simply supply those fonts
along with your .tex source. If other
people need to compile your
source, simply ensure that they have
everything they need to
compile it?
Well I don't know if redistribution of Adobe
fonts is permitted (I
would assume not) so this really isn't a
(legal) option.
