Thanks for the info.

It does look like a bug to me, but it's always best to try and identify the
cause before facing the challenge of a legitimate bug submission.

On Mac OS (same info as my first post), the duplicated "mu" is only present
in the pdf output of pdf(), for both grid and base graphics. Cairo and
quartz don't duplicate the symbol. postscript() works fine too (understand
'as I expect') but I haven't been able to check without converting the file
to pdf first.


library(grid)
pdf("testPdf.pdf")
plot.new()
text(0.5,0.5, expression(mu),cex=10)
grid.newpage()
grid.text(expression(mu),gp=gpar(cex=10))
dev.off()

postscript(file="testEps.eps")
grid.newpage()
grid.text(expression(mu),gp=gpar(cex=10))
dev.off()

quartz(file="testQuartz.pdf",type = "pdf")
plot.new()
text(0.5,0.5, expression(mu),cex=10)
dev.off()


library(Cairo)
Cairo(file="testCairo.pdf",type="pdf",dpi=72)
plot.new()
text(0.5,0.5, expression(mu),cex=10)
dev.off()


system("ps2pdf testEps.eps testEps.pdf")

# not necessarily enlightening ...
#system("cat testPdf.pdf",int=T) # only this one has duplicated symbols
#system("cat testEps.pdf",int=T)
#system("cat testQuartz.pdf",int=T)
#system("cat testCairo.pdf",int=T)
