Question Add domain + "The password contains the characters that are not allowed"

[Chrisa]

Is there a list that shows the acceptable characters for passwords when adding a domain?

Plesk generates the following error but (unhelpfully) does not indicate which characters it has a problem with. Could not find this info in documentation.

"The password contains the characters that are not allowed"

 

[IgorG]

The following characters are not allowed in the passwords:

' - single quote

" - double quote

That message has since been modified to contain the offending character(s):
The password contains the characters that are not allowed: §
However it would be nice if plesk would already say so when it checks the password strength and not only when OK is clicked.

Apparently only ASCII characters are allowed to avoid surprises with utf-8?
