Sorry for the confusion. I asked about woff files on a Debian email
list, and the response [1] was I should file a bug report against the
package that was choking on the woff files. That package would be the
package containing XeTeX. So I agree, not a Debian bug, but Debian would
receive a bug against the XeTeX package, and presumably forward that bug
to the XeTeX maintainers (which I would imagine are on this xetex list
already).

I had missed that, thank you for pointing it out to me.

Well... while I agree that we should do something in XeTeX to handle 
this, I also think it is a poor decision on Debian's side to mix .woff 
files, which are explicitly intended for web deployment, alongside .otf 
files that are expected to be available in the local GUI desktop 
environment. These are two distinct categories of resource, and it would 
be more appropriate to keep them separate.


More generally, I think it's a bad idea for a distro or package or 
whatever to install multiple copies of the "same" font (e.g. both 
TrueType and Type1 formats) with the same name where fontconfig will 
find them both.

Why Debian? I meant it is more a xetex problem so I would add a bug
report there.

You don't need the full path. This here works fine for me (arial is
a system font and the other is in the texmf tree):

\font\test="[arial.ttf]:color=FF;mapping=tex-text" at 20pt 
\test
alblbl --- 

\font\test="[texgyrecursor-regular.otf]:color=00FF00" at 20pt
\test
alblbl ---

But you won't be able to use font options like /GR (at least that's
what xetexref says).

AFAIK, Windows users don't have this problem. Unless a user or an
installer installed with WOFF files where fontconfig would find them,
there would not be a problem. The issue comes up when the Debian/Ubuntu
packages would place the WOFF files were fontconfig finds them.

How do I specify the extension? If I am using plain XeTeX and have a
line such as

\font\bodyfont="Andika New Basic/GR" at 12pt

where do I put the extension? I can place the font name in brackets [],
and include the extension, but then I need to supply the entire path to
the font file.

Thanks, Bobby

On the whole I would agree with the debian answer: applications like
xetex/xdvipdfmx shouldn't try to use fonts it can't handle. 

On windows where fontconfig is used only by xetex I would try to
blacklist the faulty fonts with a -pattern (I don't know
if it would work for the woff-problem) in the fontconfig
configuration but I don't think that there is an easy way to do
something like this on linux -- all configuration would affect other
application. So imho some other way to blacklist fonts/font types
for xetex/dvipdfmx is needed (luaotfload has a configuration file
for this).

That's the general answer. On the practical side: It can only help
if you can avoid to put the font somewhere where is disturb xetex.
And xetex users shold avoid "vage" font loading by adding the
extension if possible.
