Hello, all.
JIS X 0213 is revised at Feb 20, 2004 (as Amendment 1).
Short summary:
* Notorious parenthesized UCS code points
(Unexisting UCS code points were given in parentheses) are gone.
* 25 JIS characters are mapped to a sequence of two UCS characters.
These mappings are identical to ones I had been reported here:
cf. http://www.xray.mpe.mpg.de/mailing-lists/perl-unicode/2002-04/msg00024.html
* Mapping of JIS 2-93-27 (plane-row-cell) is fixed to U+9B1C,
in concordance with Unicode 3.2.0.
In JIS X 0213:2000, it was mapped to U+9B1D.
* Representative gryphs for 168 Kanji are revised
(their mappings to UCS are not changed).
* 10 kanji are added to level 3. (total: 11233 graphic characters)
All new kanji are one of variants for a level 1 or 2 kanji.
These variant pairs have not been unified in UCS.

* Encoding names are revised.
(oops, these names are suffixed with "2003",
but the revision is published in 2004! Too late!).

* Escape sequences for JIS X 0213:2004 Plane 1 is revised
(It's a proposal? I don't know when it will be registered so).
New final byte : 5/1 (ascii 'Q')
Old final byte : 4/15 (ascii 'O')
Final byte for Plane 2 is left as it was [5/0 (ascii 'P')].
