Cool, thanks, I didn't know about that. I'll give it a try. This still
doesn't fix the root cause, though.
Cheers, Ilia

Hi Ilia,
You may want to have a try of the showtext package
(https://github.com/yixuan/showtext). Below is a quick example:
library(showtext)
showtext.auto()
pdf("test.pdf")
## Use the "sans" font family provided by the showtext package
## font == 3 means italic font face
plot(1, xlab = "Unicode characters: \u00C0 \u00C6 \u00D8",
family = "sans", font.lab = 3)
dev.off()
## Same for SVG
svg("test.svg")
plot(1, xlab = "Unicode characters: \u00C0 \u00C6 \u00D8",
family = "sans", font.lab = 3)
dev.off()
Best,
Yixuan

Interesting. I did not have the package installed, but I did at some point
extract Helvetica from some MacOSX font files and R was using that just fine
until 3.3. This is how the plot looks in 3.4 (still using Helvetica):
https://ptpb.pw/HikX.pdf . After removing Helvetica, installing the
ttf-mscorefonts-installer package, and running fc-cache --force the plot
looks like this: https://ptpb.pw/CM8A.pdf
Also note that the standard pdf device works fine: https://ptpb.pw/3Ml1.pdf
, it's just the cairo devices (both pdf and svg) that have the issue.
Unfortunately I need to use cairo_pdf due to unicode characters in axis
labels.
Cheers, Ilia
