Special letters on axis, R plot

Question

I have a problem with special letters in plots. Here's an example:

plot(1:10,1:10, xlab="Idő", ylab=" ")

After I export the plot in pdf, which is what i need, the "ő" letter disappears from the text and becomes simply "Ido". How can it be solved?

Thanks!

The problem is with the default encoding of the pdf device in RGui. You'll have to open and close the device from R:

pdf(file="test.pdf", encoding="CP1250")
plot(1:10,1:10, xlab="Id\U0151", ylab=" ")
dev.off()
