Status: For review by WG2

This document describes updates to ISO/IEC 10646:2003 that would address issues that were discovered by the Project Editor outside the amendment process. 1. Usage of the ‘composite character ’ term. The sub-clause ‘20.4 Variation selectors ’ uses the term ‘composite characters ’ without defining it. Only the term ‘composite sequence ’ is specified in clause 4. The intent was to describe characters that are decomposable, i.e. that can be decomposed into alternate, but equivalent composite sequences. Because the term ‘composite character ’ is only used once, it is probably not necessary to add a new formal term definition, but only to amend the sentence containing it as follows: Furthermore, no sequences containing variations selectors and a mix of combining characters or decomposable characters (i.e. that can be decomposed into an alternate, but equivalent composite sequence) will be defined. It should be noted that the sentence above was moved by Amendment 3. It should also be noted that the editor instruction concerning that move is incorrect. It should say “Replace the third and fourth paragraphs with the following ” instead of “Replace the second and third paragraphs…”. 2. Unicode version references In the sub-clause ’20.4 Variation selectors’, the 5th note contain an outdate reference to Unicode 4.0. It should be updated at minimum to Unicode 5.0, or later version, to maintain synchronization between ISO/IEC 10646 and the Unicode Standard. In addition, the annex M should contain a new entry for Unicode 5.0 as follows
