Some emojis work, others don't

[ThomasWilli]

Hi

Thank you for this package, it looks promising! However, it seems that only some emojis can be displayed, while others don't work at all. Do I need to install other «stuff»? Thanks for your help!

Here's my sessionInfo:

post source code for me to reproduce the 'not working emoji'.

please make sure you are not using RStudio, which is not supported.

Sorry, wasn't aware that it does not work in RStudio. The example runs perfectly now. Thanks!
