The first part has been implemented in: https://github.com/jonathanslenders/python-prompt-toolkit/commit/f311c7524a318ba2bf264bc2024388706e0485e8

Cursor movement still needs to be done. Right now it's still possible to position the cursor in the middle of the decomposed character.

It seems that it doesn't work for double width chars.

Hi @randy3k, thanks for noticing! This commit should fix that: https://github.com/jonathanslenders/python-prompt-toolkit/commit/c6ebc96aa3278a6136d76e4ba98308044293a8a2 Can you please try again?

Notice that it still requires multiple cursor movements (left/right arrow) to move across these characters.
