Naoyuki, do you have collation data for Japanese surrogate characters?

surrogate paired character list in JIS X 0213:2004

Hi Karl, I attached the list of surrogate characters in JIS X 0213:2004 in UTF8 and 
UTF16 (\u notation). I extracted this list from
http://w3.kcua.ac.jp/~fujiwara/jis2000/jis2004/jisx0213-2004.html

Oops, sorry, I misunderstood your request.
But I guess the first column data  (kuten) in URL chart like 1-14-02 can be used
as collation order
for these characters. I will attach surrogate paired list with this data.

Hi Naoyuki,  what we need to update is the charset collator,

http://l10n.openoffice.org/source/browse/*checkout*/l10n/i18npool/source/collator/data/ja_charset.txt?rev=1.2

I think the surrogate characters need to be inserted into the list, can I just
use the list in,

http://w3.kcua.ac.jp/~fujiwara/jis2000/jis2004/jisx0213-2004.html

to replace ja_charset.txt?

Hi Karl,

I looked current ja_charset.txt and data in w3.kcua.ac.jp. Please do not replace
current ja_charset.txt with data in w3.kcua.ac.jp. I believe current
ja_charset.txt has more reasonable order at least for Kana part. I do not know
where ja_charset.txt came from, but if we can get updated version (with JIS X
0213:2004) from the same source, then we should update with it. I mean, if we
can't, then I feel we should leave it as is for now. I do not see benefit to
break backward compatibility, and actually I failed to find added surrogate
paired characters collation data which OOo can utilize on the net.

Since we don't have collation data for those surrogate pairs, I will close this
issue as WONTFIX.

close.
