Doug, Peter, and Michael already provided good responses to this suggestion by William O, but here is a little further clarification.

Approvals aren't *finished* until both the UTC and ISO JTC1/SC2/WG2 have completed their work. The JTC1 balloting and approval process is a lengthy and deliberate one, and there are many precedents where a proposed character, perhaps one already approved by the UTC, has been moved in a subsequent ballotting in response to a national body comment. Only when both committees have completed all approvals and have verified they are finally in synch with each other, do they proceed with formal publication of the *standardized* encodings for the new characters. The reasons the UTC "approves" characters and posts them in the Pipeline page at www.unicode.org in advance of the actual final standardization are: A. To avoid the chicken and the egg problem for the two committees. Someone has to go first on an approval, since the committees do not meet jointly. Sometimes the UTC goes first, and sometimes WG2 goes first. B. To give notice to people regarding what is in process and what stage of approval it is at. This helps in precluding duplicate submissions and also helps in assigning code points for new characters when we are dealing with large numbers of new submissions. > These minor > additions to the Standard could be produced as characters are accepted and > publicised in the Unicode Consortium's webspace. The UTC can and does give notification regarding what characters have reached "approved" status. The Pipeline page at www.unicode.org is, for example, about to be updated with the 215 new character approvals from the recent UTC meeting. > If the characters have not > been accepted then they cannot be considered ready to be used, yet if they > have been accepted, what is the problem in releasing them so that people who > want to get on with using them can do so? See above. Standardization bodies must move deliberately and carefully, since if they publish mistakes, everybody is saddled with them essentially forever. In the case of encoding large numbers of additional characters, because the UTC has plenty of experience at the kind of shuffling around that may occur while ballotting is still under consideration, it would be irresponsible to publish small revisions and encourage people to start using characters that we know have not yet completed all steps of the standardization process. > Why is it that it is regarded by the Unicode Consortium > as reasonable that it takes years to get a character through the committees > and into use? Because with the experience of four major revisions of the Unicode Standard (and numerous minor revisions) and the experience of three major revisions of ISO/IEC 10646 (and numerous individual amendments) under out belt, we know that is how long it takes in actual practice. > The idea of having to use the > Private Use Area for a period after the characters have been accepted is > just a nonsense. Please take a look at: http://www.unicode.org/alloc/Caution.html which has long been posted to help explain why character approval is not just an instantaneous process. The further along a particular character happens to be in the ISO JTC1 approval process, the less likely it is that it will actually move before the standard is actually published. Implementers can, of course, choose whatever level of risk they can handle when doing early implemention of provisionally approved characters which have not yet been formally published in the standards. But if they guess wrong and implement a character (in a font or in anything else) that is moved at some point in the ballotting, then that was just the risk they took, and they can't expect to come back to the committees bearing complaints and grievances about it. If you, for example, want to put U+267F HANDICAPPED SIGN in a font now, nobody will stop you, but bear in mind that this character is only at Stage 1 of the ISO process -- it has not yet been considered or even provisionally approved by WG2. Not only is the name likely to change (based on all the issues already discussed), but it is conceivable that WG2 could decide to approve it at some other code position instead. It is even conceivable that WG2 could *refuse* to encode the character. There have been precedents, where a UTC approved character met opposition in WG2, and the UTC later decided to rescind its approval in favor of maintaining synchronization of the standards when published. --Ken --Ken
