I want the term to be more low-level and physical, than abstract or conceptual. That is, I'd like the term to be outside of the Unicode specialized terminology. To that end, I think octet works well. >>> Reference to unallocated code points SHOULD NOT be treated as an >>> error; associated bytes SHOULD be processed using the system default >>> method for denoting an unallocated or undisplayable code point. >>> >>> Code points that do not have the requisite attributes to qualify as >>> part of an emoji_sequence should also not be treated as an error, >>> although you probably want to allow the system to alternatively >>> display them normally (rather than as an unallocated or undisplayable >>> code point). >> >> I think your comment addresses a different issue than the cited text is >> meant for, but I also might be misunderstanding. > > Probably, but I think it bears saying something about how to handle > code points without the Emoji property set. IMHO they should be > handled as undisplayable. This steps into user interface design, more than interoperable emoji labeling and transport. As such, it's outside of this specification and outside of the IETF's expertise. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
