Do emojis work in Roblox TextLabels?

If you build the text in a script, watch out for string.sub. Emojis are several bytes each, so cutting a string by byte position can slice one in half and you get garbage or a box. The utf8 library (utf8.len, utf8.offset) counts characters properly.

most of them do. the empty boxes are usually one of these: - flags. those are made from two characters combined and roblox doesn't render them - newer emojis, the font roblox ships is behind the latest unicode set - skin tone or combined ones (families, people with jobs etc) sometimes split in two or show a box for shop buttons an ImageLabel with your own icon is the safer bet anyway. looks the same for everyone and you pick the art style.
