Problem of a server gettext message.

Hi.

I think this has many problems. However, by the reason the release 
is approaching, this is not the situation which I'm looking at leisurely......

Server message has a problem by 8.3beta4 on windows.

The situation is this.

1. initdb -E UTF-8 --no-locale
This is C locale.

2. Japanese local message of po file to setting(share/locale/ja) .

3. set the client_encoding is SJIS.

4. action error message is made to send from server.
It is crash....

5. The reason is because the message which a server outputs is SJIS.

Version 8.2.x outputs an English message. It did not look at a problem.
Then, I consider as LC_MESSAGE for a server message, or wish a back patch.

Is there any good solution method?
