Alberto,
you simply need a font that has those characters. For example on 10.6 this
works:
plot.new(); plot.window(0:1,0:1);
text(0.5,0.5,"??",cex=10,family="Hei")
You may want to check your system for fonts that you can use (those that have
chinese characters when you click on them in Font Book). There are a lot of
fonts that work like STSong, STFangsong, LiSong Pro, AppleMyungjo, GungSeo etc.
Cheers,
Simon
