yes, I definitely see your point here. The concept of a bar is indeed more than cosmetic, even if perhaps the differences are easily taken into account.

For those who use other editors are habituated very deeply to a specific behaviour of the bar, and anything that deviates from this feels subtly but clearly broken.

I've checked with some editors, e.g atom (using huge font is easiest), the selection works just like the jump (so it is a selection of zero length). When you click to the right of the middle of a character and then drag to the left, the character will be included. If you drag to the right it will not be included.
