I know a woman who insists on using a numerical password because she can enter it no matter which language the keyboard layout is in. Therefore I suggest an option that passwords be accepted depending only upon which keys are pressed, no matter which keyboard layout is selected. For example, the Hebrew letter "ש" is on the same key as English "a". So if the Ubuntu password is "a" then the password "ש" would also be accepted.
I do not think that this would reduce security as much as it may look. This does not reduce the amount of unique characters that one could use as a password. If crackers were to try to brute force a password, they would still have to check all the Latin characters individually, not like with case insensitivity. Also note that this feature would be optional, that is, a user would have to explicitly configure Ubuntu to do this.
