[ESS] umlauts in graphics

[Christian Montel]

Hi,

I've got a problem stuffing umlauts into my r graphics (please don't be 
too angry if I missed the correct answer somewhere in the archives....).

Here's a minimal example:

DatMat <- rbind(c(67.42,91.24),c(67.14,90.81))
graphic <- barplot(DatMat,
                   beside=TRUE,
                   names.arg=c("Überlauf","Ärgernis"),
                   main="Übertitel",
                   ylim=c(0,100)
                   )


That snippet works fine in the R console (2.2.0), meaning it displays 
the umlauts. Using Ess 5.2.11, the umlauts are quoted by squares in the 
graphic. I use Emacs 21.3.1 and Windows2000. Can anyone give me a hint?

Thanks in advance,
Christian
