What are the differences between the following OpenType number sets?
- Small Capitals numbers (c2sc) and Denominators (dnom)
- Numerators (nums) and Superscript (sups)
As I understand it, SmallCaps and Denoms share the same baseline, but not necessarily the height, depending on the design. The former is aligned with SC letters, and the latter with the lower numerals in fractional form.
Numerators and Superiors should share their size, but the vertical position is aligned with the upper number of the fractional form in the former case, and with how the superscript relates to standard letters in the latter.
Am I missing something important? Thank you.
