Thanks, but it is very hard to understand what exactly do you see without seeing some kind of screenshot. If the problem is the visual appearance of the Emoji sequences, the best description of how they look is a screenshot, so please post that here, and let's take it from there. One possible reason to see a box is that your font doesn't support some sequences, but there could be other reasons, see bug#63731.
