Okay, so it seems the problem is at my end. I have my Windows fonts
installed in /usr/local/share/fonts and this is referenced in
/etc/fonts/local.conf like so:

        <?xml version="1.0"?>
        <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
        <!-- /etc/fonts/local.conf file for local customizations -->

Well, I decided to try commenting out that dir element and restarting X.
Now when I go to

the page is displayed correctly but Mozilla/Firefox pops up a warning
dialog saying the following:

        To properly display the MathML on this page you need to install
        the following fonts:
        For further information see:

Huh? (a) the page is displayed correctly, and (b) I am certain that the
Symbol font is included in FC2:

        $ xlsfonts | grep symbol
        -urw-standard symbols l-medium-r-normal--0-0-0-0-p-0-adobe-fontspecific
        -urw-standard symbols l-medium-r-normal--0-0-0-0-p-0-iso10646-1

Admittedly, the above Adobe fonts are Type 1 fonts, but Xft understands
both Type 1 and True Type fonts, doesn't it?

Anyway, I guess I can re-enable my Windows fonts if I remove the Windows
Symbol font, which was probably the one causing the problems, but I am
rather puzzled by Mozilla telling me that I don't have a Symbol font
installed in that case. Do others get the same warning?

TIA, Darren
