[R] unicode&pdf font problem

[tdenes at cogpsyphy.hu]

Dear List,

I would like to print a plot into pdf. The problem is that the character
\U0171 is replaced by a simple 'u' (i.e. without accents) in the pdf file.

Example:
# this works fine
plot(1,type="n")
text(1,1,"print \U0171")

# this fails
pdf("trial.pdf")
plot(1,type="n")
text(1,1,"print \U0171")
dev.off()

I found an earlier post at
http://www.mail-archive.com/r-help@r-project.org/msg65541.html, but it is
too hard to understand at my R-level. Any help is appreciated.

Regards,
  Denes
