This contribution paper proposes the correction procedure of the error described in WG2 N2271

�Proposed to amend two source code change in BMP CJK Unified Ideograph block (TCA)�.

 

The requirement from TCA is reasonable and it is necessary to correct the error described in the N2271.

However, to avoid the confusion of na�ve users, simple correction approach should not be taken.

 

Problem:

Because the characters in error is so similar for na�ve user, the pulished ISO/IEC 10646-1 is delivering a message of� �those two are to be UNIFIED�.� Thus, it is necessary to state �those two are not unified any more�.

 

Proposed solution.

1.      Publish the corrigendum for ISO/IEC 10646-1:2000.

2.      The reason for the corrigendom should NOT be simple relocation of the sources.

Such as simple change of:

5B90 T source to T4-225B, and make T source of� 2-19F7 to T4-2625 should not be done

And also move T2-662B from 7921 to 7934 only should not be done.

 

(but, actual result of the corrigendum should be so)

3.      State clearly on the corrigendum as follow:

3-1.      Disunify T source form 5B90 and 7921.�� The reason of disunification should be �mistake�.

3-2.      Add source T4-225B for U-5B90,

Add source T2-662B for U-7934��� then

3-4         Merging source T4-2625 to Part-2-19F7 does not requie formal process.

Just sneak it in to ext-B (and superCJK) while its development process.

 

I hope if corrigendum describes above, it can provide a message that those are not to be unified clearly to the user and may prevent the misuse of the UCS.
