Those are not duplicate characters. There is a case-pairing glottal stop and a non-casing glottal stop. That is a functional difference. > or the NEW TAI LUE and TAI THAM scripts. These are not duplicate scripts. (And no, I'm not interested in debating this with you.) > We also have the principal of the separation of scripts. I do not think it is wise to encode some "neo-Mayan" number system because some magazines have used them decoratively in foliation or because some school-children spend a cultural week or two doing Mayan maths before getting back to regular decimal algebra and geometry. That is not a sufficient usage scenario to rush forward with an encoding. I believe that it would be prudent to avoid encoding these numbers until the entire script has been examined properly. Preliminary work I did in 1998 on Mayan turned up nearly 1200 characters. 44 of these were calendrical. 20 were numeric. It would be foolish to risk a mistaken encoding of this important script in a rush to encode 5% of the whole just because that 5% *seems* to someone to be "safe". He doesn't know if it's safe or not. We owe it to Mayan civilization past and present to do a proper job here. Michael Everson * http://www.evertype.com/
