I've looked at this many times and it really doesn't have anything to do with width. That was my first guess too. It has to do with how characters like emojis are rendered by a given terminal. So, we could probably fix it for one terminal and that would break it in another terminal because they're not rendered the same.

You can also see this by opening our test file in nu_scripts/assets/gh-emoji.json

i just tested kitty, wezterm, alacritty, xterm and gnome terminal and they all display it same way. you dont need to handle all possible emoji combinations, especially bullshit combining, but you can handle most of the cases, especially eastern hieroglyphs, if you just account for correct wcswidth. elvish, for example, handles this case correctly.

Unfortunately, we don't live in an entirely Linux world, so other platforms need to work too, namely MacOS and Windows. Mitchell @ Ghostty has a good handle on this and wrote about it here https://mitchellh.com/writing/grapheme-clusters-in-terminals. Seems like the best way to go would be to support mode 2027.
