Of course, we're talking here about the same set of TeX constructs that are
supported by the competition, which is only a subset of TeX syntax.

Indeed, and nothing prevents a backend from doing it. In a text object,
you can still get access to the text string through the "string" property.

The competition supports currently 3 text interpreter: none, tex and latex.
The latex interpreter is a special case as the competition uses an embedded
latex engine, supporting the complete latex commands. The tex interpreter
only supports a limited subset of commands (sub/super-scripts, symbols...),
but is usually enough for common situations.

What I'm talking about here is to address the tex interpreter (the 'none'
interpreter can be viewed as a special case where no interpretation is
made).
