Yes, this request is already in our database.

Currently, you can already "fake it" somewhat by converting your text object to a PlanetPress Talk object and adding translate() commands before and after your sub/super script characters.

Granted, it's not the most convenient way of doing things but until we implement the feature in the application, it's unfortunately your only option.

Thanks for your suggestion!
