Your assumption was correct.

Well, I suppose that there may well quite justifiably seem to be a 
logical inconsistency in me not being enthusiastic about some particular 
markup solutions and then suggesting what is another markup solution. In 
my mind there is a big difference in that my suggestion does not involve 
overloading the original meaning of the character with another 
distinctly different meaning. So in my mind my request for encoding the 
teletext control characters as displayable characters in plane 14 with 
the specific and documented intention that they may, but need not, be 
used in a markup manner did, and still does, seem to build upon what 
Doug wrote. Yet maybe I am pushing the envelope too far, though maybe 
not. I opine that, notwithstanding any possible logical inconsistency 
with longstanding custom and practice, encoding the teletext control 
characters as displayable characters in plane 14 as I suggest is the 
best long term solution. However, I am open to other suggestions if 
anyone can think of a better way to proceed.

I was building on what Doug wrote.
