Dear all,
Sorry that I was confused by the word ¡°new character¡± in Wang Wei¡¯s email. Now it is clear that this is an issue purely with CGP-JGP, not IRG. The character ©– U+3007 has been encoded  since the first version of Unicode/CJK.

Concerning the question about ©– and Áã, I have some points:

1.     They are the corresponding member in the two common frequently-used subsets ¡°©–Ò»¶þÈýËÄÎåÁùÆ߰˾ÅÊ® ¡° and ¡° ÁãÒ¼·¡ÈþËÁÎé½Æâ°Æ¾ÁÊ°¡±.

2.     The traditional form of    ¡° ÁãÒ¼·¡ÈþËÁÎé½Æâ°Æ¾ÁÊ°¡± are  ¡° ÁãÒ¼ÙEÈýËÁÎéê‘Æâ°Æ¾ÁÊ°¡± used in Taiwan and Hongkong, Some characters may have more forms, say Èþ or²Î.

3.     ©– and Áãmay regarded as somehow low case-uppercase relation, or simplified -unsimplified ones. Whatever you consider they are, they have the same meaning as ideographic number zero. By LGR definition ,they are VARIANT each other. Even if they are simplified ¨C traditional relationship which still belong to VARIANT concept .

4.     I remember that TLD-LGR does not require variants must have the ALL meaning(s)  are the same.
In summary£¬ It is OK to treat ©– as a variant of Áã in TLD-LGR scope.
Thanks,

Zhang

Hello,

I agree with Professor LuQin's point.

Pls kindly consider the following words in section 2.6 of RFC5892(for IDNA )


2.6<https://tools.ietf.org/html/rfc5892#section-2.6>.  Exceptions (F)


   F: cp is in {00B7, 00DF, 0375, 03C2, 05F3, 05F4, 0640, 0660,
                0661, 0662, 0663, 0664, 0665, 0666, 0667, 0668,
                0669, 06F0, 06F1, 06F2, 06F3, 06F4, 06F5, 06F6,
                06F7, 06F8, 06F9, 06FD, 06FE, 07FA, 0F0B, 3007,
                302E, 302F, 3031, 3032, 3033, 3034, 3035, 303B,
                30FB}

   This category explicitly lists code points for which the category
   cannot be assigned using only the core property values that exist in
   the Unicode standard.  The values are according to the table below:

PVALID -- Would otherwise have been DISALLOWED

00DF; PVALID     # LATIN SMALL LETTER SHARP S
03C2; PVALID     # GREEK SMALL LETTER FINAL SIGMA
06FD; PVALID     # ARABIC SIGN SINDHI AMPERSAND
06FE; PVALID     # ARABIC SIGN SINDHI POSTPOSITION MEN
0F0B; PVALID     # TIBETAN MARK INTERSYLLABIC TSHEG
3007; PVALID     # IDEOGRAPHIC NUMBER ZERO

It means that U+3007 is only allowed as the number zero, otherwise it will not allowed in use in IDNA protocols.

Áã can be used to express many meanings besides the number zero, but ©– can be only used as the number zero In IDNA.

©– is a special code point in IDNA while Áã is a normal code point.

so it may be not proper that  ©– is regarded as  a variant to Áã based on IDNA protocols.
Best Regards

Ö÷Ì⣺ [ChineseGP]RE: question about ©– and Áã
Dear Wang Wei,

What is the U code of this Japanese?  I think U+3007 being considered the simplified form of Áã is a good one, simply consider it as variant is not as good.  But, U+3007 is considered a CJK symbol, not a CJK ideograph.



Best regards,

LuQin

Subject: question about ©– and Áã

Dear Prof. Lu, Prof. Li and Prof. Zhang
×𾴵ĽÀÏʦ£¬ÀîÀÏʦ£¬ÕÅÀÏʦ

       JGP provided its latest repertoire in which a new character ©– was added.
       do you think ©– should be an independent character, or, a variant to Áã £¿

       ÔÚ×îеÄÈÕ±¾×Ö¼¯À¼ÓÈëÁË×Ö·û¡°©–¡±
       ÄãÃÇÈÏΪ©–ÊÇ·ñÓ¦ÉèΪÁãµÄÒìÌ壬»¹ÊǶÀÁ¢³É×Ö£¿

       Looking forward to your suggestion

Regards
WANG Wei
