Fix PDF showing inifinity instead of bullets

I've had this problem for a long time, sometimes a PDF was created with a font that doesn't get mapped properly and the bullet points show up as inifinity symbols.

I found this post for Ubuntu: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/551977

$ fc-match Symbol
symbol.ttf: "Symbol" "Regular"

A workaround is adding this code to /etc/fonts/local.conf and the bullets would appear:

<match target="pattern">
 <test name="family">
  <string>Symbol</string>
 </test>
 <edit name="family" mode="prepend" binding="same">
  <string>Standard Symbols L</string>
 </edit>
</match>

$ fc-match Symbol
s050000l.pfb: "Standard Symbols L" "Regular"

This worked perfectly in Arch for me.
