I can't seem to get the axis text showing unicode, but when i try it in geom_text it shows up just fine.

Is there a way to do this or...?

ggdata <- data.frame(text = c("text 1", "text <U+2665>", "text ♥"), value = c(1, 3, 5), stringsAsFactors = FALSE)

ggplot(data = ggdata, aes( x = text, y = value, label = text)) + geom_bar(stat="identity") + geom_text(nudge_y = 1)

rplot

It works for me, but you're probably on windows. Can you please confirm the simpler reprex below still illustrates the problem for you?

df <- tibble::tibble(x = c("a", ""))

ggplot(df, aes(x, x)) + 
  geom_text(aes(label = x))

The problem is stil there. And yes, I'm one a Windows - just tried to run your code on a linux server I have, and there it worked fine.

The root cause seems to be a buglet in R. On windows, I see:

x <- c("a", "")
format(x)
#> [1] "a       " "<U+2665>"

😞

Ok, pretty sure I fixed it, just by avoiding the use of format() (which I'm not sure why was necessary in most cases anyway). Please let me know if this doesn't fix the problem.
