Meta: ␄ (https://en.wikipedia.org/wiki/End-of-Transmission_character) isn’t the right control character when footnotes follow; ␃ (https://en.wikipedia.org/wiki/End-of-Text_character) is a better fit, and ␌ (https://en.wikipedia.org/wiki/Form_feed) would be a decent choice too.

(I write comments with footnotes in the same style as you, but use “—⁂—” as the separator, via Compose+h+r (name from the HTML tag horizontal rule). Good fun being able to use Compose+E+O+T, Compose+E+T+X and Compose+F+F in this comment; I added the full set to my .XCompose years ago.)
