Hi Simpetus 

Thanks for reaching out in the Lucidchart Community! Unfortunately emojis are not currently supported in Lucidchart. However we are continuously looking for how we can make our product more useful and effective for our users and your feedback is the best way for us to do that. If you’d like to see unicode emojis supported in Lucidchart in the future would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

Thanks for your request!
