    Becaus then every lunatic will feel encouraged to step in and burden the people in charge with loads of “inventions”. This would lead to the standard becoming completely un-manageable.

    There *is* a rigorous procedure already. Rigorous and cumbersome but fair.

    > What I am suggesting is that for new electronic system items that it is unreasonable and a needless barrier to progress for someone to need to first establish widespread usage using the Private Use Area before encoding in regular Unicode can take place.

    It is a barrier there are reasons for. And the PUA may serve your purposes for getting in what you want, given you can testify *some* (not neccessarily: widespread) usage. That is quite a practical option actually, including some sort of security for all parties involved.

    I know this issue is a particular serious one in Mathematics. It is similar serious in Linguistics. As for that subject, the progression of the MUFI may give a good example how it can work: some specialists gathering and setting up character lists, furnishing the PUA with characters, file a proposal and present proof of usage to UC and ISO – encoding proceeded. That’s the way the A72x block was “invented”.
    I do very special composing work upon early musical notation. Same situation: the standard “as is” provides less than a tenth of the special characters needed. Naturally. Needless to say that I can’t wait until Unicode has granted me what I need for that sort of text. Anyway, the Private Area is the realm of peace to gently grow the seeds for the future :-)
