An alternative is to use the my.symbols function from the TeachingDemos package (improvements are welcome).

Subject: [R] Windows OS, R and unicode

I'm trying to use the biological female and male signs in R2.5.1 under 
Windows XP. I can access and insert these symbols using word-processors.

In general these should be available as \u2640 and \u2642 but I can't 
make them happen in R using (say) text(5,5, "\u2640") message "invalid 
\uxxxx sequence"

I've replaced Arial with Arial unicode MS in Rdevga and I've tried 
various setlocale options with no success (the Murrell/Ripley examples 
(Rnews 6/2) do work of course ... so I feel I should be able to do this 
myself, but after several hours it is time to ask for help). 

I understand from Google results that users on Mac OS and Linux aren't 
facing this problem ...
