Comment 3 for bug 1793879

Je peux répliquer sans même faire une recherche filtre
Je ne suis pas un pro des ''locales''

$ locale
LANG=en_GB.UTF-8
LANGUAGE=en_GB

locale -a | egrep 'fr_CH|iso8859'
en_GB.iso885915
en_US.iso885915
fr_CH
fr_CH.utf8

Je rajoute les locales CH
# cat /etc/locale.gen | grep fr_CH
 fr_CH ISO-8859-1
 fr_CH.UTF-8 UTF-8

$ sudo locale-gen fr_CH.ISO-8859-1
Generating locales (this might take a while)...
