award/medal emojis loses colors

[manasseh]

Problem Description

I tried out the {emo(ji)} package with award/medal emojis glued to a table created by {gt} but the saved table resulted in a color loss in both emojis. Kindly, help.

Code Snippets

emo::ji_glue(award("Gold"))
emo::ji_glue(award("Silver"))
emo::ji_glue(award("Bronze"))

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Expected a result similar to this or a better display of medals

You've made a good quality reprex.
I was going to suggest you to raise an issue with gt, I suspect a webshot issue, then i saw that someone raised this previously so its a known issue.

Going one step further, in advance of gt officially changing their functions to use weshot2 rather than webshot, we can go ahead and make our own save function based on theirs with the webshots swapped out.

library(webshot2)
new_gt_save <- function (data, filename, path = NULL, ..., zoom = 2, expand = 5) 
{
  filename <- gt:::gtsave_filename(path = path, filename = filename)
  tempfile_ <- tempfile(fileext = ".html")
  tempfile_ <- tempfile_ %>% gt:::tidy_gsub("\\\\", "/")
  gt:::gt_save_html(data = data, filename = tempfile_, path = NULL)
  if (!requireNamespace("webshot2", quietly = TRUE)) {
    stop("The `webshot2` package is required for saving images of gt tables.", 
         call. = FALSE)
  }
  else {
    webshot2::webshot(url = paste0("file:///", tempfile_), 
                     file = filename, selector = "table", zoom = zoom, 
                     expand = expand, ...)
  }
}

Thank you!
It worked.
