Font fallback. HN specifies Verdana, Geneva, sans-serif. Geneva has the six characters mentioned. The rest will be rendered using a different font that covers more parts of Unicode, or that covers Unicode math specifically. With the built-in system fonts, that would be Cambria Math on Windows and one of the STIX fonts on macOS.
(Source: Firefox → Inspect Element → Fonts tab of the right Inspector pane. Chrome can do that too in a slightly different place, macOS Safari is too user-hostile to have this feature.)

- Someone 6y agoI guessed that, but still can’t figure out what makes ℂℍℙℚ special. Looking again, I notice ℕ is taller, too, but not bolder. ℂℍℕℙℚℝℤ is much more “I can see why a font would have these, but not others”. That solves the issue enough for me. (And, by the way, iOS doesn’t have Geneva, but it has a version of Verdana)
