Default profile pic issues / questions

Hi all gurus!
I have a nextcloud installation (of course) and i have a strange issue. when i ad dnew users with hebrew names, the default profile pic that is created is just blank boxes instead of the users initials. i was wondering 2 things:

  1. is it possible for nextcloud to display the initails in non-english language?
  2. is it possible (as admin) to set a default profile pic for all new users?

thanks!

they arent really pictures, meaning if you e.g. sync to your iphone, they wont have a picture.
as for displaying hebrew characters… well it doesnt show any special characters at all so I guess you would have to use alphanumeric characters, make a feature request in the contacts app section or if you know how to code, implement it and suggest to merge
