    I recommend using StixGeneral for symbols.
    See http://www.stixfonts.org/
-   This is the default for the symbol font if you have it installed.
+   To install on Ubuntu, try:  
+
+         sudo apt-get install fonts-stix
+
    Other good choices are: Lucida Grande, Lucida Sans Unicode, 
    or DejaVuLGC Sans Mono.
