German Umlaut problem with Z-Push and WebApp in Docker environment

Jackdd

Hallo Community,

I’m migrating my current Debian 9 (OMV) Kopano installation to Debian 11 Docker environment using the latest official Kopano docker containers from docker hub (currently in Hyper-V VM on windows) with a modified docker-compose configuration without ldap from the demo installation on github.
After sorting out all problems and get anything working again I stuck on the german umlauts ä,ö,ü for 2 days now. The umlauts are wrong on folders in Webapp and in mail and appointment subjects in Z-Push (Outlook) and Webapp. The contact names are also wrong.

I’m using my current database, which was created 2013 with zarafa on Synology NAS. In 2016 I could fix the umlaut problem by removing setLocale() in zarafa config.php and setting the de_DE.UTF-8 locale in php fpm directly. This workaround does not work my current kopano “production” installation from 2018. There I had to change the LANG environment for apache server to fix the german umlauts.
Because the docker environment is using Kopano Web server all know fixes seems not working.

I tried setting locale in kopano server.
Map host etc/default/locale with de_DE.UTF-8 locale readonly into docker containers.
Change or add setLocale(…) in kopano.php or config.php in docker containers and restart the services inside the containers.

No luck and not further ideas. On new mails the umlauts working. I don’t know where the conversion problem occurs. In Kopano server or php.

My current debian 9 “production” environment uses the following versions:

kopano-server: 8.7.81.219
web-app: 3.5.8.2339
z-push: 2.6.2

Docker container using the following versions:

kopano-server: 11.0.1.101
web-app: 6.0.0.22
z-push: 2.6.2

Thanks for any help and advice.

@thctlo Thanks for the tip. But it doesn’t help. The umlauts are still wrong.

Because we have only 2 users and about 1GB mails and appointment I will save anything locally in outlook, create users from scratch and copy anything back over outlook. So hopefully the umlaut problem is gone.
