Answer 1

If the question is, “Can I use them,” then the answer is “possible.” . You will need to test them thoroughly to make sure your applications support extended ASCII characters in passwords. If you use different operating systems or systems in a mixed language, it is somewhat less likely that they will be compatible, because you will begin to understand different problems with encodings. There are many versions of the so-called extended ASCII set, and they can be presented in very different ways.

• As long as the characters are valid for entering a password, they can be rude, as easy as any other character. A short password with strange characters is still many times weaker than a longer password made of alphanumeric characters.
