Re: Flag tags

So I could propose, say, the Pigpen cipher?

To the degree that the use of the substitution is "style", no. Fraktur
and Insular forms have been unified for Latin. But these styles are also
recognizable (if not to all users, then a significant number). And,
there's a benefit in identifying them primarily with the Latin alphabet,
and only secondarily with the precise style.
The "dancing men" are more like Braille. There's one source where they
have been given a particular "mapping" to the Latin alphabet, but that
mapping is not the only one possible. The whole point of them is that
the actual mapping has to be known or discovered each time.
So, yes, these would have to be encoded by shape, not by target.
