Exclude SOME Special Characters in Passwords

Dear all,

is there a way to avoid SOME special characters in the password seed. This is sometimes very annoying, when Nextcloud generates password to externals and you as an inviter have to tell it on the phone. Please be advised, that I don’t want to send the password via mail or change it to some password with a easier seeding. So Characters like ^~ß} are sometimes difficult to tell on the phone.
