Unicode problem in 2.0.7-pre1

[Hiroshi MIURA]

Hello, 

I find the bug in utils/make_unimap.c in samba-2.0.7-pre1.
It use codepages/CP???.TXT  that come from Unicode.org.
You can see Codepage to Unicode mapping in this table.
But you cannot determine mapping from Unicode to Codepage in some case, 
because in CP932, there are some "1:n" map from unicode to CP. 
How do you judge which one you should adopt?

I made a Unicode to CP932 map table, "CP932UC.txt". and made a code 
that handle this table, "make_unimap2.c" and some patch to "installcp.sh"

and.. make L10N patch to "lib/kanji.c", that fix problem 
described before.  

there are in 
http://plaza24.mbn.or.jp/~moh/samba/samba-pre2.0.7-JP.patch

Please fix samba-2.0.7-pre1....
