[BioC] R fonts: character set (male/female symbols)

[J.delasHeras at ed.ac.uk]

This is a more general R question, not specifically BioC, but I  
imagine is something that the "bio" people here must have encountered  
at some point.

I would like to include the symbols for male and female in a legend  
for a plot. How do I obtain that?
Is there a function that will show me all the characters available in  
the font that R is using?

I have been looking in the manual etc but I haven't found what I'm  
looking for.

Anyone?

Thanks!

Jose
