Just a start, but to get it encoded you need more. Examples of using the cc logo in plaintext _might_ help.
Make that "widespread examples of using (cc)" since a character is not available in plain text. Such examples might help, and so would widespread use of this character in other contexts where copyright is normally used, and which conceivably could have been in plain text if it had been the copyright symbol;
I disagree with the 'we don't do logos' argument in its most simplistic form for this case as there is a clear analogy with an established symbol that *is* supported in plain text. So the argument does not hinge on the plain text vs rich text question, but on whether the level of usage indicates that it should be recognized by a *worldwide standard* such as Unicode.
If several million users were using this symbol daily, and given its plain text analogue we would quite likely encode it, 'logo' or not.
The Euro symbol, was from its start analogous to $ which answered the 'is it a character' question. Given its backing by the EU, widespread use could be assumed, and it was encoded *before* practical use of it began.
The creative commons movement does not have the same clout as the European quasi government with now 420 or so million subjects ;-) so copious(!) examples of widespread actual use would be needed to 'start the discussion'.
