Is that limited to the kitty terminal? I don't see any compatibility notes on Kitty Graphics Protocol nor your TUI project - which given the TUI label I would expect to work on any terminal?
The kitty terminal graphics protocol is implemented by kitty, WezTerm, Konsole, and others I believe.
It does work in any terminal, but the emoji support is limited to terminals that implement this graphics API.
