emo::ji won't render in knitted documents

Question

I want to insert a few emojis into my rmarkdown document.

devtools::install_github("hadley/emo")
library(emo)
emo::ji('turtle')
#

However, when I knit my document in the emojis won't render. In this example the chunk render doesn't work but the inline one does:

    Example for not rendering:

    ``` {r}
    library(emo)
    emo::ji('smile')
    ```

    Inline example:
    `r emo::j('smile')`

But then here the inline doesn't work as well:

<font color='skyblue'>*Hey, you! Marine biologist! I have need of your services!  
A sea turtle begins its life amidst great danger, and not very many of them make it to the water. See, I'm working on a big budget movie - think "Saw", but with turtles. Anyway, let's make some realistic numbers of turtles for me to... **keep alive.***</font> `r emo::ji('turtle')`

I've updated everything I could think of (R, Rstudio, all markdown-related packages) but alas.

On Linux the works for me in both cases. The produces only an empty box in RStudio, but works when I open the HTML file with a browser. — Ralf Stubner, Sep 16 '19 at 12:24
I use Windows 10. Neither emoji appears when I open in browser. — Ronny Efronny, Sep 16 '19 at 12:41

After hours of searching I found that the problem was with the native encoding of my session. As presented in this answer, I did File -> Reopen with Encoding... and selected UTF-8, and for good measure selected UTF-8 to be the default in the future. Knitted the file - worked like a charm.
