I have found the cause. That is, file categories.t is not correct.

For example,  http://ftp.unicode.org/Public/UNIDATA/UnicodeData.txt
says:

3400;<CJK Ideograph Extension A, First>;Lo;0;L;;;;;N;;;;;
4DB5;<CJK Ideograph Extension A, Last>;Lo;0;L;;;;;N;;;;;
...
4E00;<CJK Ideograph, First>;Lo;0;L;;;;;N;;;;;
9FEF;<CJK Ideograph, Last>;Lo;0;L;;;;;N;;;;;

However, categories.t is:
    {CAT_Lo, 0x3400, 0},
    {CAT_Lo, 0x4DB5, 0},
...
    {CAT_Lo, 0x4E00, 0},
    {CAT_Lo, 0x9FEA, 0},

Therefore, the script mkcategories which generates categories.t
should be fixed.
