I've asked this question before, but I've never had a satisfactory response, so I'll ask it again now that Unicode 4 is due to be released soon.
Section 10.1 of the Unicode Standard, as well as Blocks-4.0.0.txt, give the range of the CJK Unified Ideographs block as U+4E00 through U+9FFF, whereas at the top of the CJK Unified Ideographs code chart it clearly states "Range: 4E00–9FAF", and does not show the columns 9FB0-9FBF, 9FC0-9FCF, 9FD0-9FDF, 9FE0-9FEF and 9FF0-9FFF. Is there a reason for this discrepancy ? Given that new CJK unified ideographs are added to supplementary CJK blocks (CJK-A, CJK-B and CJK-C), and I understand that no more characters are intended to be added to the basic CJK block, why then are U+9FB0 through U+9FFF reserved for the CJK Unified Ideographs block ? Surely these eighty code points would be better utilised if freed for use by new scripts. Andrew
