Thanks Adrien, I sorted this issue. It was the case that docker image had no specific locale set so it was the fallback to POSIX/ASCII
Once I compiled the docker image with correct locale everything was fine: FROM ubuntu MAINTAINER "R" ENV DEBIAN_FRONTEND noninteractive RUN apt-get update -q && apt-get install -y \ locales \ mysql-client \ gnucash \ gnucash-docs \ yelp \ dbus-x11 \ --no-install-recommends \ && rm -rf /var/lib/apt/lists/* \ && rm -rf /src/*.deb # LOCLES: uncomment chosen locale to enable it's generation RUN sed -i 's/# en_GB.UTF-8 UTF-8/en_GB.UTF-8 UTF-8/' /etc/locale.gen # generate chosen locale RUN locale-gen en_GB.UTF-8 # set system-wide locale settings ENV LANG en_GB.UTF-8 ENV LANGUAGE en_GB ENV LC_ALL en_GB.UTF-8 # verify modified configuration RUN dpkg-reconfigure --frontend noninteractive locales RUN groupadd gnucash \ && useradd -g gnucash -G video gnucash -m # run gnucash as non-privileged user USER gnucash ENTRYPOINT ["/usr/bin/gnucash", "--logto", "stderr"] -- Sent from: http://gnucash.1415818.n4.nabble.com/GnuCash-User-f1415819.html _______________________________________________ gnucash-user mailing list gnucash-user@gnucash.org To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user If you are using Nabble or Gmane, please see https://wiki.gnucash.org/wiki/Mailing_Lists for more information. ----- Please remember to CC this list on all your replies.
