First bad#1 is the correct version (except for the copy&paste), the merging of emoji parts should happen after you move the cursor out, it's ok for this behavior to be contextual > Byte-wise, this should be rendered as a single emoji. It will be right after you've finished editing! No magic cursor movements. And it should allow you to move "inside" emojis so you could edit the second modifier to something else (and worth some great UI that could guide you as to which options are available), which would be impossible in the "correct" TextEdit, where you'd have to recompose a new emoji from scratch
