I know this is common in the TLG, but as you say, they assume it is just omicron (an assumption repeated in a message just received from them). But, I am trying to get across that that is wrong: it represents neither papyri nor Byzantine MSS.
...
So is there not a good reason to treat this as a distinct character, to be assigned to a Unicode codepoint ?
Raymond, based on what you have said, I would agree. A variety of visual representations, clearly distinct from the omicron as formed in the same documents, suggests a separate character. Would you be able to write up a proposal to encode such a character, or at least an informational document including illustrations of different forms of the Greek zero, preferably in proximity to differently formed omicrons? Nothing is going to happen unless the UTC receive such a document, and you sound like the best person to prepare one.
