Rendering mathematical notation in a text terminal can work well for
very simple formulae but breaks down for more complex formulae, like

J_v(z) = \sum_{k=0}^{\infty }{{{\left(-1\right)^{k}\,\left(z\over 

(from the Maxima link above).  As I've said before, there is no way we are
going to write code in texi2any to parse this and produce text output.

(We are talking about terminal emulators here of course, not the
obsolete physical text terminals where it's questionable whether many
of the characters like ≠ or √ would have worked anyway.)
