Two thoughts:

- keep track of the baseline and size of characters, if the baseline is =
slightly shifted (upwards -> superscript, downward -> subscript) and the =
size is smaller than surrounding characters, it's possibly a superscript =
or subscript character

- be aware of the fact that some fonts contain glyphs for superscripts - =
then baseline and text size would be the same; in such cases you'd have =
to look up via the Unicode code point whether you have encountered a =
superscript.
