I use utf-8 encoding within the Icinga2 configuration files. Everything works correctly, but the display is strange: in Icingaweb2, characters that are not part of ascii-7 are shown incorrectly.
As a specific example, the display name of a user contains an umlaut, ä, which is displayed as ä in Icingaweb2.
I am using the https://github.com/jjethwa/icinga2 container to run both icinga2 and icingaweb2.
What should I do?
