sub and superscripts: without «_» and «^»

[Uwe Brauer]

Hello

I asked this on auctex-dev but it might be question concerning core
functionality of GNU emacs:

It is possible to display super and sub indices lowered and rised, but
the «_» and «^» are still visible.

(Xemacs can display, based on very different implementation indeed sub
and super scripts without the «_» and «^», however relies on a orphaned
package)

Are there any plans to implement such a feature?

Thanks

Uwe Brauer
