sf + ggplot + ragg doesn't print degree symbol

[mhpob]

library(sf)

nc <- sf::st_read(system.file("shape/nc.shp", package="sf"))


library(ggplot2)
map <- ggplot() +
    geom_sf(data = nc)


ragg::agg_png(width = 900, height = 450)
map
invisible(dev.off())

png(width = 900, height = 450)
map
invisible(dev.off())

[thomasp85]

I cannot reproduce this. What system are you on? And does the issue persist with the development version?

[mhpob]

Using Windows 10 -- just re-installed the development version of ragg and the problem persists. Here's my sessionInfo:

[thomasp85]

Thanks - I'll try to check this out on windows.

[thomasp85]

I can reproduce on Windows

[thomasp85]

OK, so apparently the symbol font does not provide a Unicode character map but only understands the ancient Adobe Symbol encoding... this is fixable but I'll have to think about the path of least resistance (esp since it is a windows only problem)

[MargaretSiple-NOAA]

I have had this same issue recently, though I can't pinpoint when it started happening. When I use ggplot() + geom_sf(), degree symbols appear as little boxes, as they did in @mhpob 's example above. When I change to R 4.2.1 instead of 4.2.2, it resolves the issue. I have noooo idea what is happening.

Here is a reprex that will reproduce this same issue on my Windows 10 machine:

# Map test based on geom_sf() help file
nc <- sf::st_read(system.file("shape/nc.shp", package = "sf"), quiet = TRUE)
ggplot(nc) +
  geom_sf(aes(fill = AREA))

which produces the following:

I suspect that this is related to my windows fonts somehow, but any additional insight would be appreciated. I will struggle mightily before developing a hacky workaround. Thank you!

@MargaretSiple-NOAA - Ditto here - having the exact same problem with the Degree symbols not rendering.

[MargaretSiple-NOAA]

@grwhumphries Does it resolve if you use R 4.2.1 or 4.2.0 instead of 4.2.2? I am not sure if the version is the issue but that's how I was able to resolve the issue temporarily. Not ideal, but it did work!

[sraul1]

Just updated to 4.2.2 and have this issue as well. Resolves itself in 4.2.1. here is my sessionInfo() (sorry for all the packages loaded, too deep into something to start a new session, I'll update with a cleaner environment soon)

I switched back to 4.2.1 and the issue was resolved. Unsure what's going on there. Hopefully gets picked up

[thomasp85]

Thanks for the reports everyone... I'll see if I can figure out what is going on - weird how the R version can affect this
