A superscript glyph would in my view normally be larger than a glyph for 
a combining superscript character. The reason is that the former just 
has to appear raised and smaller, while the latter has to fit somehow in 
the space above x-height.
The typeset example shows kerning of true superscript and subscript 
glyphs, not a combination in the sense we understand combining 
characters. This can be seen in the original, where the upper half of 
the composite shape would not fit above x-height.
Since this is not a "standard" notation, but an innovative, yet 
single-use device, it does not merit a standardized plain text 
representation - that is not unless we have many other examples of 
similar overlays of letter pairs.
