As mentioned in our meeting today I have worked on tooling to extract
webfont code point usage from pages with the purpose of
auto-generating optimal subsets for the exact content.

I believe these tools can be adapted to out purpose of figuring out
what code point diffs a user navigation across multiple pages will
encounter.

There's already a debug mode in the existing subsetting tool, which
should enable you to have a peek into the dataset that drives it.
This, of course, needs to be isolated and repackaged to fit our
purpose.

Example command lines that will show some debug output:

npx subfont -d https://www.w3.org/Fonts/WG/ -o TMP_DELETE_ME --no-recursive
npx subfont -d https://jakearchibald.com/ -o TMP_DELETE_ME --no-recursive
