I'd like to add a special locale `strip` to the emoji transliterator to easily remove all emojis from a string. It would only work with valid input/emojis.

Removing emojis from a string is not easy. Regexes are complicated and most of the time not up-to-date with the latest Unicode versions. I thought we could leverage the new transliterator 😄
