Some characters becomes ?? in pdf templates after upgrade

[novastream]

Hi,

After upgrading to 9.0.0 (via cli) all special chars in my PDF-templates are displayed as ??.

They are displayed correctly when editing the template.

Some chars that are not displayed correctly:
å ä ö á

Any ideas whats wrong?

I noticed the same thing today, in my case it's the letter “ß”.
But after checking, the other German characters don't work either.
