143170 - Can't search GBK/GB18030 characters in Advanced Search with an IMAP account

Status: RESOLVED INVALID

(MailNews Core :: Internationalization, defect)

Description

[Jeesun Cho]

Can't search certain characters in GB2312
Build: 0508 Branch
OS: Chinese Windows 98

Steps:
1. Using IMAP account (not POP), send yourself a message with the following
chars in either subject or body;
Ӄ
�U
For example, I sent a message with "Ӄ" as a subject.
2. Bring up the Advanced Search and search for a message which contains "Ӄ" in
its subject
3. No matched are found.

So far, these are the two chars that I encountered. Other single char search
worked fine.
I did the same thing on POP account. It worked OK.

Those two characters mentioned in Jeesun's report are GBK characters.
Same problem occurs to the other GBK characters. I noticed that there is no
warning message when I send a gb2312 mail which contains characters that are in
GBK range but not in gb2312 range. And search for those GBK specific characters
fails no matter the mail is sent in GB2312 or GBK.

And I don't see this problem with quick search.

Changed the platform to all since I see the problem on linux 05/09 1.0.0 build.

Same search problem with advanced search for gb18030 characters, like �9ø8�9ø9.
The difference is that it does give charset warning message if a GB18030 char is
included in gb2312 or gbk mail.

cc to taka, does the server support GBK/GB18030?

Comment 8

[Frank Tang]

this problem only with IMAP4 and GB18030. Currently, Enterprise market in China
is not our focus, nsbeta1- it.

According to taka, this is a server issue. If the server does not recoginze
GB18030 then the search does not work. Invalid, since this is not a client problem.
