No, I mean even getting color emojis to work was trouble, it just had problems with variable width characters.
But I haven't used it in years, maybe it's patched already. Sure, give it a try, doing so will do no harm 🤷
Urxvt used to be fast with very minimal feature set — pretty much in the vein of alacritty. It's probably the other way around though, since it came earlier 😅
