[arch-general] "error: unknown encoding UTF8: using iso88591 as fallback"

[Ralf Mardorf]

Hi,

for some time past I get

  error: unknown encoding UTF8: using iso88591 as fallback

when running GTK2 and GTK3 apps, Pluma, Claws Mail, Evolution. Other
apps, perhaps Qt apps, might be affected too.

There are no issues when using those apps, the terminal just shows
these messages.

  [rocketmouse at archlinux ~]$ locale -a
  C
  de_DE
  de_DE at euro
  de_DE.iso88591
  de_DE.iso885915 at euro
  de_DE.utf8
  deutsch
  en_GB
  en_GB.iso88591
  en_GB.utf8
  en_US
  en_US.iso88591
  en_US.utf8
  german
  POSIX
  [rocketmouse at archlinux ~]$ cat /etc/locale.conf
  LANG=en_US.UTF-8
  [rocketmouse at archlinux ~]$ cat ~/.config/locale.conf
  cat: /home/rocketmouse/.config/locale.conf: No such file or directory
  [rocketmouse at archlinux ~]$ sudo nano /etc/locale.conf
  [rocketmouse at archlinux ~]$ cat /etc/locale.conf
  LANG=en_US.utf8
  [rocketmouse at archlinux ~]$ sudo shutdown -r now

It doesn't make a difference, I still get the error messages, when
running a new session.

Regards,
Ralf
