Hi,
My problem is that I wanted to knit an .Rmd file with the setting dev = 'pdf', to get all the plots in pdf format. The problem is that my language is Hungarian so I would need "ő" charachter in the figure, which is missing.
As an example the legend title "egy főre eső" becomes "egy fore eso".
The problem do not emerge, when dev = "png" or anything else, but I need pdf.
Thank you for your help in advance.
I think you need to play with the argument of pdf() function so that it supports a font with those characters. It uses postscript if I understand well. Graphic devices is not something I find easy.
You could also try other pdf devices
cairo_pdf device from grDevices,Cairo::CairoPDF()
You could also be interested in this article about how to use fonts with R graphics.
and about the showtext package

Hope it helps.
If you find the answer, please share.
It may be in fact an encoding issue. If I use the unicode code, it gets printed correclty
pdf()
plot(cars, main = "egy f\u0151re es\u0151")
dev.off()
cairo_pdf solved the issue. Thank you very much!
Cool !
It did not in my case but maybe because my French computer is not setup for Hungarian characters. Only using the unicode utf8 \u*** worked for me.
Glad it works for you ! Cheers.
