Problem with emoji menu in French

In French, there is always a space before the colon ( : ) punctuation mark. Thus, I always get the emoji menu when I want to use this character ; which is not handy when I want to go to return to the next line right after this character (to introduce a list item).

I see two solutions to this problem: (<= problem occurs here in French)

- create an option "Use `::` to open the emoji menu (instead of `:` )" in the settings,
- put a "new line" menu item at the top of the emoji menu (or a blank menu item), so that the default behavior is to go to new line when the user does not want to place an emoji but wants to go to a new line.

There might be other solutions.
