Hi @jorgemanrubia, could I ask for a code review? |

Hi @jorgemanrubia or @flavorjones, is there any chance for this to be reviewed and merged/rejected? |
This is already handled in functions like `expandSelectionInDirection` which won't select a half of emoji etc. but always the whole surrogate pair. The solution here is the same, if the cursor is placed in the middle of a surrogate pair, it will be moved to the end of the pair. Similarly a selection will either select both or neither.

I've rebased this onto current @Thomaash can you say a bit more about how this problem occurs in an application -- how is the cursor ending up in the middle of a multi-byte code point? |
