That would be application-dependent, I would say. Some would probably
like to see the text as written, while others would like to see the

Hmmm. I wouldn't expect that to be a problem in this case.

That's true, but on the other hand, when people propose new characters
one of the reactions seems to be "can you show a font that contains
this character"? But I guess what you are saying is that if the symbol
can be encoded using existing characters having a font that contains
it is not enough.
I was thinking of a font where this was a basic character, and not
composed from smaller parts, however. I don't know if that makes any
