I am using Nextcloud version 22.2.2. I have customized the mail for welcoming new users like stated in the Nextcloud docs (https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/email_configuration.html#using-email-templates).
I managed to change the logos, buttons and the text. Everything is fine now except for one thing:
The mail should be bilangual (English and German). The problem now is that as soon as I put the German special characters (ä ö ü …) into the email body, the whole text is shown blank.
The charset on the template is set to UTF-8. I have also tried to change the default language to German, which did not help.
Do you have any ideas for me?
Thank you in advance!
