It took me some time to figure out why I cannot log into the admin panel after the setup and trying starting all over multiple times.
Until I started to read the setup scripts and noticed that probably the strict encoding to US-UTF8 for python to consume does not inlcude the characters like ä and ß etc^^.
I have tried using different passwords, but somehow always hit one of those characters.
I think a warning at some place might be enough.
Cheers!
