Hi all,

I recently noticed the messages below in my /var/log/messages.

I followed the localisation guide https://wiki.gentoo.org/wiki/Localization/Guide and noticed that I had LC_COLLATE="C" instead of "C.UTF-8". After a locale-gen + env-update && source /etc/profile the message is still there:

/var/log/messages:
Code:
Sep 21 06:33:04 mobiletux org.kde.kded.smart: Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8. Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead. If this causes problems, reconfigure your locale. See the locale(1) manual for more information.

My locales:
Code:
# locale
LANG=de_DE.utf8
LC_CTYPE="de_DE.utf8"
LC_NUMERIC="de_DE.utf8"
LC_TIME="de_DE.utf8"
LC_COLLATE=C.UTF-8
LC_MONETARY="de_DE.utf8"
LC_MESSAGES="de_DE.utf8"
LC_PAPER="de_DE.utf8"
LC_NAME="de_DE.utf8"
LC_ADDRESS="de_DE.utf8"
LC_TELEPHONE="de_DE.utf8"
LC_MEASUREMENT="de_DE.utf8"
LC_IDENTIFICATION="de_DE.utf8"
LC_ALL=


How can I get rid of this? Thx!

have you define the LANG in /etc/locale.conf ?
if so, you need restart the session to take effect.

Hi,
I don't have a /etc/locale.conf. LANG is defined here:

/etc/env.d/02locale
Code:
# Configuration file for eselect
# This file has been automatically generated.
LANG="de_DE.UTF-8"
LC_COLLATE="C.UTF-8"

oh yes , /etc/env.d/02locale is the right place.

you can check the process to see if env appplied:
Code:
cat /proc/[pid of the process]/environ | xargs -n 1 -0 | egrep "LANG|LC_"

Hi all,

same Problem here.

The only process which is running with LANG=C is "/usr/libexec/sddm-helper --socket /tmp/sddm-auth-6b2f03c5-0c01-43dc-aa47-3762b3a3c25d --id 1 --start /usr/libexec/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland --user <user>"

I couldn't find any configuration which sets LANG to the mentioned value. Any Ideas?


Greetings
Matthias

"ANSI_X3.4-1968" is what us mere mortals call 'ASCII'. :-) Is ASCII referenced anywhere in your locale-related settings?

No ASCII referenced anywhere.

Code:

mkrsn@client02 ~ $ cat /etc/locale.gen
en_US.UTF-8 UTF-8
de_DE.UTF-8 UTF-8


Code:

mkrsn@client02 ~ $ cat /etc/env.d/02locale
# Configuration file for eselect
# This file has been automatically generated.
LANG="en_US.utf8"


Code:

mkrsn@client02 ~ $ env | grep "LANG\|LC_"
LANGUAGE=en_US
LC_ADDRESS=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_MONETARY=de_DE.UTF-8
LC_PAPER=de_DE.UTF-8
LANG=en_US.utf8
LC_TELEPHONE=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
LC_NUMERIC=de_DE.UTF-8


Code:

client02 ~ # grep -ri "LANG=C" /etc/
/etc/conf.d/auditd:AUDITD_LANG=C

client02 ~ # grep -ri "ASCII" /etc/
/etc/texmf/texmf.d/20sizes.cnf:% ignored. If file names in sources and DVI or XDV files are ASCII

Code:

client02 ~ # locale -a
C
C.utf8
de_DE.utf8
en_US.utf8
POSIX


hmm.... I don't have any clue where C comes from....


[edit1]
It seems that having C there is some sort of default behavior. I've checked it on different machines (ubuntu's & headless gentoo's, gentoo's with X or wayland), they all have C there.

Yeah, the "C" locale is the default locale.

Doing some searches, i found this comment (via this discussion):

Quote:
It is the long standing incompatibility between locale support in KDE/Qt and locale support in glibc/POSIX. KDE supports much wider range of locale combinations than glibc.

See as example

Hi,
marking it as "solved" since it doesn't seem to be a Gentoo system configuration thing.
