IDN compatibility requirements for applications

Applications must be IDN-compliant in order to work with internationalized domain names. The following sections lists some of the applications that are IDN-compliant along with their requirements.

- Important: If your application is not IDN-compliant, you must use the ASCII-encoded representation of the domain name to access the domain. To view the ASCII-encoded representation, refer to your account details provided in the email sent by your administrator.
  If you are using the Microsoft Windows platform, you need to install native fonts on your system to ensure that the non-ASCII characters are rendered correctly.
