LC_TIME="ru_RU.UTF-8"
LC_COLLATE=C
LC_MONETARY="ru_RU.UTF-8"
LC_MESSAGES="ru_RU.UTF-8"
LC_PAPER="ru_RU.UTF-8"
LC_NAME="ru_RU.UTF-8"
LC_ADDRESS="ru_RU.UTF-8"
LC_TELEPHONE="ru_RU.UTF-8"
LC_MEASUREMENT="ru_RU.UTF-8"

bash-4.1$ su
Password: 
bash-4.1# locale
LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=
bash-4.1# exit
exit
bash-4.1$ su -l
Password: 
root@darkstar:~# locale
LANG=ru_RU.UTF-8
LC_CTYPE="ru_RU.UTF-8"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_COLLATE=C
LC_MONETARY="ru_RU.UTF-8"
LC_MESSAGES="ru_RU.UTF-8"
LC_PAPER="ru_RU.UTF-8"
LC_NAME="ru_RU.UTF-8"
LC_ADDRESS="ru_RU.UTF-8"
LC_TELEPHONE="ru_RU.UTF-8"

LC_ALL=

If I use any another locale, en_US for example, problem return again.

Running su will not setup the environment properly. You need to run "su -" instead. This will setup root's environment properly.

Thanks! On 13.0 all worked with "su" only. I will develop a habit to use "su -"

Hi,

13.1 has a bug in libmisc/env.c from shadow package. It was introdused with security fixes for GNU gettext.

libmisc/env.c at line 254 in sanitize_env() has typo '!=' and should be

Code:

			if (strchr (*cur, '/') == NULL) {

instead of

Code:

			if (strchr (*cur, '/') != NULL) {

Without this fix su breaks LANG, LANGUAGE, LC_* environment variables when they hasn't '/' but should be vice versa.

Fixed in upstream in rev.3090.

"su -", "su -l", "su -l root" start a login shell so execute /etc/profile that calls /etc/profile.d/lang.sh that sets LANG environment variable.
