Significant population? Some school kids somewhere? A couple of local magazines? Local usage is important, yes. Tengwar is used by lots of folks. > If we encode the numerals now, then once the script is eventually fully > encoded, one of several things will happen: I don't think you can possibly know what can happen. > • We will have (through responsible forethought) guessed right on the > metadata, and the pre-encoded numerals will be usable as-is in the general > encoding Guessing right is not adequate. Once a character has been encoded it can NEVER be removed.

Again, I don't know what you mean by "metadata", so I don't know what you think but if Mayan numbers are expected to > • We will have guessed wrong on the metadata, and the decision is made > that a retroactive fix is the best solution, given that it (say) impacts only > documents which mix Mongolian with Mayan numerals. I don't know what you think a "retroactive fix" is but it is unlikely that any "informative" as opposed to "normative" fix would be possible. > • We will have guessed wrong on the metadata, but anyway need to encode > multiple versions of the number glyphs, so having used up 20 codepoints for > modern users of the Mayan numerals is no big loss.

The Universal Character Set is an International Standard. We cannot go in encoding things we do not have confidence in. > I think the latter 2 possibilities are both acceptable and unlikely.

We must encode Mayan properly. Michael Everson * http://www.evertype.com/
