Indeed. I happen to think the whole math alphabet thing was a dumb
mistake. But even if it isn't - and incidentally in some communities
there is or was a convention of using blackboard bold letters for
matrices, which justifies all of them -:

Either superscripts are being used mathematically, in which case you
can use mathematical markup, or they're being used with very specific
semantics, as in the phonetic modifier letters. For the latter case,
there is a standard. First you get your letter recognized by the IPA,
then you encode it. The IPA doesn't recognize arbitrary superscripts.
