[R] [Rd] italic font on cairo devices in R 3.4

[Yixuan Qiu]

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
