I get relatively inconsistent results in terms of which font is chosen to display a given symbol. The pair of fonts that I mentioned (Ubuntu Mono and Symbola) was just an example; my question is about configuring fallbacks for any given pair of fonts: it could be Source Code Pro and Asana Math instead of Ubuntu Mono and Symbola, for example.

Is it enough to augment the default fontset? Changing the :height of the 'default font creates a new fontset, which doesn't respect the fallbacks that I configure. Hence my using
(dolist (ft (fontset-list))
(set-fontset-font ft 'unicode (font-spec :name "Ubuntu Mono"))
(set-fontset-font ft 'unicode (font-spec :name "Symbola") nil 'append))

𝓟 is displayed using `Latin Modern Math' in emacs -Q, it seems. In any case, Ubuntu Mono and Symbola were just two examples.
