and now to see how emoji rendering is completely broken, put a gear u+2699 text variant and emoji variant in some html and set the font to menlo in one element, and monaco in another element and then view it in chrome, safari desktop, and safari ios, and also select and right click on it in chrome, and maybe also post it into the comment section of various websites. Every single combination of text variant and emoji variant will be displayed in complete randomness :)
