No UTF-8 in dates

I used this cookbook for getting the right german dates. But now I have problems with utf-8. For März I get M�rz.
How can I set the UTF-8 using in date.handler config?


Sounds to me like thats actually a server issue, rather then something to be set in the handler. Are you sure the server is set to use utf-8?

Normally on my uberspace-server works utf-8 like expected but I have add AddCharset utf-8 .html .css .php .txt .js to my kirby .htaccess. Problem still exist.

Have you tried to setlocale(LC_ALL, 'de_DE.utf8')?

thanks thsi is the solution. But I set it in the config with 'locale' => 'de_DE.utf-8'.
But normally I expect that a CMS is managing this from base. Also I see there a problem if I have a multilanguage site or I have to set a config-file for every language. This is in my eyes not really smart.

EDIT: Setting the locale in the config have not the same effect.
