That's it: Junicode defines super- and subscripts only for digits and 
the few other characters in the Unicode Super- and Subscripts range, and 
those only in the Regular style, and in recent releases of the font. If 
you want more, you're better off scaling and then raising or lowering 
existing glyphs.
