Windows Terminal version

Latest

Windows build number

Latest

Other Software

No response

Steps to reproduce

  1. Open windows terminal
  2. Paste the "ℹ️" emoji (it may happen at other emojis as well, but maybe not at all and this one is definitely tested)
  3. Press backspace in order to normally delete the emoji
  4. Then see that the "ℹ️" still remains, but the writing section is left
  5. Then type another letter like "A" and see that the letter "A" merges inside the emoji

Expected Behavior

The emoji should be deleted completely after once clicking backspace and only the letter "A" should appear

Actual Behavior

The emoji and the letter "A" merge inside each other

Another important information:

This doesn't happen if you click backspace twice after placing the "ℹ️" emoji, so I think that this is technically because of the "farer" space intended to be after the emoji which is considered as another character which then is deleted technically and then this happens

I believe this is /dup https://github.com/powershell/psreadline/issues/1329 (TL;DR: PSReadline doesn't support grapheme clusters)
