Even though these critierias seem to be important to anyone that would like to get litteracy skills, these are definitely not criterias for, or against encoding in the UCS. The most importat criterai is : it is really used by a community ? For now, the main issue is effectively the fact that this script has been invented, this invention has been registered and protected in several countries (Congo RDC, France, USA, possibly others), and that the copyright claims (and patents) are restrictinh the usage because they require a licence for use by anyone. All these claims demonstrate that this is a private-use only script, even if the author pushed some educational insitutions in his countries to get some supports and researches, and organize some (limited) educational programs. Whever the script is sacred or not is not important. But the publication of his script within an open standard that is aimed to be usable by anyone (not just its encoding, but also all discussions about its usage, or the design of supporting fonts) clearly militates for blocking for now the encoding, until the author pushes to ISO and UTC a licence that will irrevocably remove all royatee-claims and all further claims that would forbid any derived work on his script by anyone else than the author (or people that only the author will approve). It is perfectly admittable however to credit the author. The proposal is definitely not an open licence that matches the targets and policies of the UCS, both in TUS and in the ISO/IEC 10646 standard. There's not even the minimum licence (with "reasonnable" cost) that is required for ANY ISO standard. So for now we have to consider this script like an artistic creation. It is protected as a whole.and still not encodable. Even if there was a compatible licence, there would still be the lack of an open community for it. It is legitimate for this script to be registered as an artisitic creation, and even legitimate for the author to claim sacred status, or legitimate for him to seek some supports in some limited educational areas. The complexity of the Mandombe layout is not important blocking issue : it also has specific 2D layout and rendering difficulties that are not encodable for now as themselves, and for which some technical description languages are still being developped as an upper layer that may be used as well for Egyptian hieroglyphs, even though the hieroglyphs cause much less problems that SignWriting. This Mandombe script is far less encodable that Sutton's SignWriting, even if both were invented. Sutton's script has demonstrated the existence of an open community and desires to be as widely used as possible For now the best way to encode the Mandombe script is by using a transcroding (to Latin, as it is the script that is used in the desription of the script) along with a higher-level description language and some rich text format to support the conversion using custom fonts.
