About superscript & subscript numbers
Superscripts and subscripts are separate characters, not formatting: a raised ² pasted as text stays raised in any system, which is why H₂O and x² survive copy-paste where styled text loses its sizing.
The digit sets are complete (0–9 both ways) but assembled from different eras of the standard, so the raised digits live in two different blocks — one reason a font can show some and box others. Test the exact digit you need.
