Special character and Emoji Picker

I would like something like this in Helix: https://github.com/nvim-telescope/telescope-symbols.nvim
> Though, this may be a better fit for a plugin.


At least searching and inserting emojis at the cursor would be very nice.
I would be happy to figure out the implementation and make a PR, but I am not sure what would be best to include. So I am looking for ideas and opinions.
