```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
- Hadley's `emo` package provides emoji support. Install it with `devtools::install_github("hadley/emo")`. 
- In order for emoji to work in Rmarkdown, you must change the file encoding of the Rmd document. Go to File -> Reopen with encoding, then select UTF-8. 
- Once you have ensured the file is open in UTF-8 encoding, you should be able to compile with emoji support. 💩     
You should even be able to paste emoji from a browser directly into the document. 😺
- It is probably a good idea to change the default encoding for all files to UTF-8 so that you don't have to deal with this issue again.

```{r emoji-test}
emo::ji("poop")
emo::ji("smile")
```
