We should expand it to 64-bit since some day the specification might be changed then:-) More seriously, Unicode is filled with tons of confusion and inconsistency IMO. Remember that once Unicode adovocates said that the merit of Unicode was it only requires 16-bit width. Now they say they need surrogate pairs and 32-bit width chars... Anyway my point is if current specification of Unicode only allows 24-bit range, why we need to allow usage against the specification? -- Tatsuo Ishii
