Not really. The ASCII specification includes caret notation for control
characters. In has been like that since the early days.
Irrelevant, I'm afraid, David.
A Usenet article is a message from a human to other humans. We can't reasonably expect other people to conspire with us in communicating via control characters. One doesn't embed ASCII 0000001s in Usenet articles.
This is the use-mention distinction. We can talk about ^A till we're blue in the face without ever actually using one. We talk about it by mentioning it, using a ^ and an A like this: ^A
No control characters were used in the construction of that paragraph.
Newsreading software that wrongly interprets ^A as "control-A" will wrongly interpret C=B^A, and is in /desperate/ need of a bug report.

The interpretation of the caret and the subsequent character will be
platform and application dependant.
Indeed. For example, the SCOS and SCOS2 applications interpret it as a printable character... which of course it is.
PS I do like SCOS.
Well, I'm glad... but a SCOS that can't shroud source code is only half a SCOS.
