Additionally please refer ragg Package

Solution

library(ggplot2)
library(ragg)

file <- knitr::fig_path('.png')
agg_png(file)

ggplot(NULL, aes(x = 1, y = 1)) + ylim(0.8, 1.2) +
  theme(axis.title = element_blank(), axis.ticks = element_blank(),
        axis.text = element_blank()) +
  annotate("text", 1, 0.9, family = "Sahitya", size = 15,
           label = "????? ") 

invisible(dev.off())

However I observed you have to download and add the font first. Hence removed :

## Sahitya font for Devanagari characters

font_add_google("Sahitya")
showtext_auto()
