[R] unicode&pdf font problem RESOLVED

[tdenes at cogpsyphy.hu]

Dear David,

Thank you for your efforts. Inspired by your remarks, I started a new
google-search and found this:
http://stackoverflow.com/questions/3434349/sweave-not-printing-localized-characters

SO HERE COMES THE SOLUTION (it works on both OSs):

pdf.options(encoding = "CP1250")
pdf()
plot(1,type="n")
text(1,1,"\U0171")
dev.off()

CP1250 should work for all Central-European languages:

Thank you again,
  Denes
