I understand that the submodule updates aren't automatic, but why isn't the bound version automatically checked out?? Is there any way to force it? I have a project with 3-levels of subm...

This may behave incorrectly1 if your String contains Unicode codepoints outside of the BMP; e.g. Emojis. For a (more complicated) solution that works correctly for all Unicode code-points, see @sibnick's solution.
