There are two reasons we might not encode a particular image as a character. I
had said:
>Many images are not appropriate for use in plain text, or have too
small a user community.
That is, you need to have something that is appropriate for use in plain text
*and* have a significant user community. As far as I have seen from the email,
there is no real evidence for a user community. If a character only occurs in a
couple of works, means there is simply not the utility in encoding it; PUA is
the right choice. There is a much larger set of documents containing the Prince
icon, but we don't want to encode that either!
