Yes, it includes all these characters. Nevertheless, these groups find it
convenient to build their own pool of data. That is exactly why the use of
the private user area is intended. Of course, in the long run, some more of
these data might end up in proposals for inclusion in future extension of
The characters in question have deliberately not undergone the unification
in question, since the preservation of the exact glyph shape is deemed of
interest. This again is a reason to use the private character area, and
again, it is a reason the number of characters needed might possibly exceed

The reason for this is very simple: This is not a big international company,
but rather some grass root projects, shareware and freeware programers
Also, if you read Mr. Maederas message again, you will find that he is
programming such an editor and that is why he came up with his proposal. He
wants to stay compatible with the way other people are handling this and at
the same time accomodate the needs of this scattered groups.

And I think, you should at least read the message and understand the problem
before coming out with such a ridiculus judgement.
