title: Username in Chinese/Japanese in Linux-Unix
body: <p>Is it possible to create a user with username in Chinese or Japanese characters in Linux/Unix? I have tried creating a user with non-ASCII characters in the username in RedHat and the useradd command does not allow it. But I can create the user by directly copying such username in the /etc/passwd file. I am not sure if such usernames are even valid and would work with everything that needs a username. I have tried googling but haven't found a definitive answer. Kindly help.</p>
  
  <p>Thanks</p>
