Yup, I meant edit the font -- I'd like to fix this properly! But I
opened Janson in Fontforge and besides the superscript 1 2 and 3 (in the
early section of the tables), there are no glyphs at all in the U207X
range and neighborhood, where the subs and supers live. So I guess
that's the source of my problem! Though they told me there was a full
range of digits...

Disappointing! But thanks again for the pointers.
