That Unicode encodes "plain text" is indeed in its fundamentals (see
2.2, Unicode Design Principles).

Also, the Criteria for Encoding Symbols speak against your characters,
on the grounds of  Jean-François objections:

http://www.unicode.org/pending/symbol-guidelines.html

"The fact that a symbol merely "seems to be useful or potentially
useful" is precisely not a reason to code it. Demonstrated usage, or
demonstrated demand, on the other hand, does constitute a good reason to
encode the symbol."

So if you can't demonstrate usage, you should at least demonstrate
demand (rather than just claiming that there might be demand).

The canonical example for adding symbols with no demonstrated usage
are apparently the currency symbols, where it is easy to demonstrate
demand (by referring to the legislation that brings the currency to
life). Welcome the NEW DRACHMA SIGN :-)
