There has been no flip-flop on such things. There were never any guarantees that musical symbols would not be part of the UCS. There will be further symbols added to the UCS, and there is no certainty of exactly what, but it is by no means open-ended. > > The range of Unicode characters is defined in > > <http://www.unicode.org/versions/Unicode4.0.0/ch02.pdf>, page 24, as 0 to > > 10FFFF(hex), which is 1.114.111 decimal - quite a bit larger than 65536, > > but quite a bit smaller than 4 billion. > > Now, yes, but I have about as much faith that that won't expand as I > now have in the "Unicode characters are sixteen bits" statement which > was true in its day. That merely indicates that you are not fully informed with the development of Unicode and ISO 10646. Nothing whatsoever has happened to increase the likelihood of the codespace ever going beyond U+10FFFF. Rather, much has been done to ensure that it does not, as reflected by recent action within JTC1/SC2/WG2 to that effect. > I did; in case you missed it, I quoted from the Unicode Standard > itself, viz.

That means that musical or dance notation and complete notational systems are beyond the scope of the Unicode Standard itself, as are mathematical formulas. That does *not* mean that the text elements -- the individual symbols -- that are used in those notation systems are necessarily out of scope for the Unicode Standard. > That appeared in the description of the "plain text" principle, > before that sentence was elided following the abandonment of that > principle. You seem to think that some principle has been abandoned, but it has not. Peter Constable _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
