Non ASCII symbols in ggplot2 plots in beamer

[agricolamz]

Bug description

When I use non ASCII symbols in ggplot2 plots in my beamer presentation I got dots. The same plot is displayed correctly on my system. Changing fonts with the package extrafonts doesn't help: the same dots.

Steps to reproduce

---
format: beamer
---

## test

```{r}
#| echo: false

library(tidyverse)
iris |> 
  ggplot(aes(Sepal.Length, Sepal.Width))+
  geom_point()+
  labs(x = "Добър", y = "ден")
```

Expected behavior

I expected cyrillic letters to appear on x and y axes.

Actual behavior

All cyrillic symbols are changed into dots.

This is a support request for knitr/ggplot2 help, so I converted it to one. Please keep it in mind for future report. Thanks!
