Superior letters and figures are not at the same height about source-sans HOT 6 CLOSED

Can you give examples of superior numbers and letters being mixed? The superior letters are intended for literary annotation, and the superior figures for scientific annotation. Is there some overlap that I am missing here?

Mathematical equations involving variables?

ha! well if you’re looking for a font for setting mathematics, this isn't it (yet). Sorry.

How about literary annotations that mix both letters and figures like 'n.1' or that use roman numerals 'xi'.

Isn't 'ordn' the feature to use to get numerator-height superscript letters?

See for example Bernard Tanguay, L’art de ponctuer, 2006, item 292 http://books.google.fr/books?id=krWENhhOZ00C&pg=PT218#v=onepage&q&f=false which gives various ways to do footnotes according to Dictionnaire des règles typographiques:
⁶, ⁽⁶⁾, (6), ^a, ^(a), (a)

If the parenthesis align with the figure in ⁽⁶⁾ they should align with the letter in ^(a) (or the superscript a should align with the superscript parenthesis). The same would apply to comma when separating several footnotes.

Will be fixed in next update.
