No matter what you call it, for a universal character encoding you will 
have to answer the question whether a symbol used in a seminal 
publication needs to be encoded for the sake of being able to correctly 
archive it without hacks like using private fonts or images.

The answer to the question rests on issues whether the publication is 
important enough to warrant very high fidelity or whether there's a 
critical significance to having that symbol over any fallback 
representation.

In this case, the "owners" of the work are still around and active, so 
that means we don't need to make decisions for them.

But imagine for a moment you were researching "Deutschtümelei" and all 
digital archives of those older versions had replaced the "idiosyncratic 
symbol" with the semantically equivalent circled R. Is that particular 
scholarship scenario interesting enough to warrant adding this as a 
historical symbol?

I'm not answering this question, but we are contemplating support for 
early mathematical notations, some of them fairly specific to particular 
mathematicians or even publishers of their work.

There's no hard lines to be found here, and for edge cases the decisions 
can seem arbitrary. But in general, this is a key part in how you 
approach any attempt at making decisions for such edge cases.
