I think that's what I suggested to Satya Narayan Mishra <snmishra at hotpop.com>:

        <match target="pattern">
                <test name="family">
                        <string>symbol</string>
                </test>
                <edit name="family" mode="append" binding="strong">
                        <string>OpenSymbol</string>
                </edit>
                <edit name="family" mode="append" binding="strong">
                        <string>Standard Symbols L</string>
                </edit>
        </match>

I use a rule like that in the /etc/fonts setup for SuSE Linux
to make Mozilla display symbols correctly and this works just fine.
