Who knew? Well, probably a lot of people. But in case you didn’t, all you need to do it put the correct code in your text and it just works.
<Label Text="&#129322 ;" FontSize="80" HorizontalOptions="Center" VerticalOptions="CenterAndExpand" />
You can get a list of codes at https://www.alt-codes.net/smiley_alt_codes.php
