 Umlaut problem solved ->Update
Forget the previous posts about the solution. I was trapped by the LANG variable of the zimbra user. I was testing with a deploy script that does ssh -c "zmmailboxdctl restart" after installing the zimlet. So with this ssh command the LANG variable was set to en_US.UTF-8. But when logging on the zimbra server it was C. That caused a lot of confusion to me and lead me to a solution that was in fact none.
So the only simple solution is to change die LANG variable of the zimbra user to use UTF-8 encoding:
Change the LANG variable in /opt/zimbra/.bash_profile to en_US.UTF-8 |
