Thanks for the hint, Eli.
I've meanwhile found out something. Not yet sure what to make of this,
but anyway:
1. In ns_init_locale, [locale localeIdentifier] returns "en_DE" on my
system, which is, I think, a consequence of my system settings, as I
mentioned (English UI in Germany).
2. man setlocale(3) says this
An argument of "" will
determine the name of the new locale taking into account the environment
variables LANG and LC_*.
So, the setlocale (LC_ALL, "") in main should initialize LC_* according
to LANG, if set. (Another question might be if that is what was
intended here, when I read the comment above that code, but be that as
it may.)
And another thing - any setlocale in ns_init_locale is moot because it
will be undone in main.
4. When I setenv LANG="en_DE.UTF-8" in ns_init_locale, the setlocale
(LC_ALL, "") returns NULL, indicating that LANG is invalid. And, indeed
$ locale -a | grep de
de_CH
de_DE.UTF-8
de_AT.ISO8859-1
de_AT.UTF-8
de_AT.ISO8859-15
de_DE.ISO8859-15
de_CH.UTF-8
de_CH.ISO8859-15
de_DE.ISO8859-1
de_CH.ISO8859-1
de_AT
de_DE
There is no en_DE...
5. When I don't use localeIndentifier, but "en_US.UTF-8", for instance,
the setlocale (LC_ALL, "") in main works like expected, and in a shell
buffer:
$ ~/emacs/master/src/ > locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=
That's all not very nice :-).
Conclusion so far, for me,
- don't selocale in ns_init_locale, only setenv LANG, or set LC_CTYPE,
maybe.
- localeIndentifier is wrong for mixed cases like "en_DE".
