Languages such as Arabic, Hebrew, Urdu, and Syriac are based on bidirectional text. Windows applications, which have a graphical user interface, support bidirectional languages. However, console applications, which employ the text user interface of the operating system console, do not provide bidirectional support. Therefore, if you localize a console application to Arabic or Hebrew, your application displays unreadable text on the console screen.

The user interface culture specifies the resources an application needs to support user input and output, and by default is the same as the operating system culture. For example, the CultureInfo.CurrentUICulture property returns an Arabic culture for an Arabic operating system. Use the CultureInfo.GetConsoleFallbackUICulture method to retrieve a culture suitable for a console application user interface. After your application retrieves the fallback user interface culture, it should assign the culture to the current user interface culture of the current thread. For more information, see the "Explicitly Setting the Current UI Culture" section of the CultureInfo.CurrentUICulture property.

The following are predefined cultures that have a different fallback user interface culture name from the predefined culture name.
