Sorry, but package Cairo is not what we were talking about here, and
problem with that on Windowsare known (to several of us at least).
The report was about the svg() device in Unix-alike R. Reports on the
Cairo package need to be sent to its maintainer (Simon Urbanek) and
I'e removed the misleading PR#.

It is a bug on your system: this is done by cairographics, and I
suspect that the version you have is broken (or possibly your viewer).
I'll attach the version I get, which does display in italics on my
system.
Thanks for that. I do see italics in your file using my 2 viewers, so
I guess that the problem is not my viewer.
At this point I should note that I can see this on Windows XP as well. Using
R 2.8.1 (CRAN binary version) and version 1.4-4 of Cairo from CRAN (windows
binary).
It doesn't seem specific to SVG, I can reproduce it with pdf or png as well.

cairographics cannot locate an italic version of the font
The following testcase tends to show the contrary:
library(Cairo)
Cairo("plot.png", width=7, height=7, units="cm", dpi=100)
plot.new()
par(family="Arial")
text(0.5,0.4,labels=expression(italic("This should be in italics")))
text(0.5,0.6,labels=expression(bold("This should be in bold")))
dev.off()
The text that should be in italics is in bold, and vice versa. This makes me
think Cairo actually finds both italics and bold, but gets confused
somewhere...
I tried replacing Arial by Times or Tahoma, or removing the call to par(),
but italics and bold are always reversed (with the correct family used).
