Why do a lot of password generators don't generate strong passwords including chinese, arabian...-characters? All generators I saw, also the included one in my password manager keepass, just output characters that are related to western languages.
In some cases would it be understandable, if the user
- needs to type his password manually into the computer
- doesn't now how to enter such characters.
Also some characters have nearly the same shape which could leed to confusion, because the input looks right, but the characters have the wrong UTF-8 code.
Uses of a password manager would not encouter the listed problems or are there other aspects to consider?
