[Dovecot] Japanese Search

[Kazuo Moriwaka]

Hello,

I'm trying to debug search command with Japanese 'ISO-2022-JP' codec.

ISO-2022-JP codec needs to keep character cases until convert to
UTF-8.

For example:
 * '\033[$B%s\033[(B' means a character sounds 'N' 
 * '\033[$B%S\033[(B' means a character sounds 'Bi' 

It causes a trouble in searches with Japanese.
I found imap/imap-search.c/add_new() makes strings uppercase 
and fixed. But search results didn't affected.. ;-)

I hope I can fix this problem in a few days. 
But I'm not clear about dovecot's source. 
If you have hints, please tell me.

thanks,
