I generated a figure using ggplot in R and I want to save it as pdf. My problem is that my figure when exported (using ggsave or pdf function) into pdf does not contain the symbol ≥ 8 in the legend. Instead I see ...8.
In addition I get a warning message:
In grid.Call(L_textBounds, as.graphicsAnnot(x$label), ... : conversion failure on '≥ 8' in 'mbcsToSbcs': dot substituted for <e2>

Does anybody know a way to correct that issue?
Thanks

The [`cairo` package](http://cran.r-project.org/web/packages/Cairo/Cairo.pdf) can help you – Ricardo Saporta May 13 '15 at 20:11

I am having the same issue when calling cairo_pdf. I would be good to have a definite fix. – eastafri May 15 '17 at 13:37
