Where feasible, probably best to move after the bold/italics/link buttons as this is not assume to be the primary button action in this group.

@jeffpaul totally agree with you, button has been moved after core format ones, see: 9647c65
The toolbar now looks like the following:

If the goal is to include the Insert special characters format button within the same core toolbar (after link and before chevron down icon), I believe we should go for a different strategy and extend blocks settings using a HOC approach.
