7、(backward compatible, default value): The password can consist of any characters including national special characters (such as , , from ISO Latin-1, 8859-1). However, all characters that are not contained in the set above (for value = 0) are mapped to the same special character, and the system ther

If your system does not support Unicode, you may not be able to enter all characters on the logon screen. This restriction is
9、limited by the codepage specified by the system language.With login/password_charset = 2, passwords are stored in a format that systems with older kernels cannot interpret. You must therefore only set the profile parameter to the value 2 after you have ensured that all systems involved support the n
