So, what encoding *should* we use for that locale?

We are certainly not going to disable pg_regress's ability to test in
non-C locales. ISTM a proper fix is an addition to the table in
src/port/chklocale.c. This example suggests actually that we need
a boatload more table entries to handle Windows locale names :-(

How about changing initdb to use encoding=UTF-8 and no-locale when the encoding of default locale is not suppoted in the server? I think it is the most frequently used combination when we cannot use the default encoding in server. The present initdb without options always fails in such environments. Using UTF-8 with no-locale is better than error. (Error is better than using wrong locale, though.) Regards, --- ITAGAKI Takahiro NTT Open Source Software Center

Then, It seems that it is necessary to consider an original initial value problem again. I consider a document publication or management. Anyway, Thanks. Regards, Hiroshi Saito

Applied with small correction --- it looked like you'd put in the wrong
PG_ENC code for GBK and BIG5. Not terribly important since we'd reject
them anyway, but we might as well reject with the correct error message.
This still leaves the policy decision of whether we want to have
initdb assume "-E UTF8 --no-locale" if it sees the current locale
has an unusable encoding. I'm not really happy with that idea
because it would disable localization of messages. I think what we
want, at least on Windows, is to switch to the "corresponding" locale
that uses UTF8. Is there a simple way to do that? Or at least some
simple recipe we can put into the documentation? "If you get this
sort of error, use this --locale setting..."

It is probably reasonable to choose UTF-8 as a server encoding when we cannot support the encoding of the current locale. A remaining issue is which we should use no-locale, locale of another encoding, or reporting error then. At least on Windows, locale of another encoding works correctly because we've already had some Windows-specific hacks. (try grep MultiByteToWideChar) In fact, we can accept options like: initdb -E UTF8 --locale=Japanese_Japan.932 -- CP932 is SJIS in nature I'll suggest to use UTF8 if the encoding is UTF-8 or NOT specified and we don't support the locale encoding on Windows, i.e. locale is always enabled on regression tests.

Here is a patch to do it on Windows.
1. Use UTF-8 if the locale encoding is not available for server.
2. Allow mismatch between server and locale encodings if the server
encoding is UTF-8.
I succeeded to run regression test on Japanese version of Windows
with the patch, but please test it on other language versions.

Hi. Um, I thinks the examination material of 8.4 by the reason for changing the feature. Of course, your proposal can be considered to obtain one solution. Then, discussion is required more.

Hmm, but does that really work safely? I think varstr_cmp() does work,
because it forces our data into wchar format and then calls wcscoll().
The thing that scares me is that various random other operating-system
calls might deliver strings in an unexpected encoding. We've been
through similar problems with timezone names reported by strftime, for
example.

Hi Tom-san.
This may be mere information...
In 8.3, when it has different encoding for every database, a locale requires C.
Therefore, I am the reason which desires C by regression test.

Hmm, I see we might need to replace all locale-aware functions to wchar_t versions, for example, wcsftime instead of strftime. It requires more tests. It should be saved for 8.4. The attached is the second plan. It uses UTF-8 and locale=C when the default locale encoding is not supported and none of encoding and locale are passed to initdb. It would help users who use the default settings (including regression test). At the moment, it reset all of lc_* variables, but it might be possible use the default locale at lc_messages, lc_monetary, lc_numeric and lc_time even if lc_collate and lc_ctype are reset to C.

I'm not very happy with this proposal, because for people who don't
actually care about non-ASCII data (which is still a lot of people),
forcing UTF-8 as the default encoding will impose pretty substantial
overhead compared to SQL_ASCII --- it turns on all those
multibyte-encoding checks.
Implicitly selecting --no-locale doesn't seem like a big step forward
either, since then you've just given up whatever you might have learned
from the locale setting. Besides, if that's the behavior the user
wants, he can specify it.
I still think that what we should try to do in the default case is find
a locale that is the same language but UTF-8 encoding.

Well, that just leaves me wondering what encoding the localized messages
would be presented in ...
