Consider the following scenario. You upgrade from the Microsoft .NET Framework 3.0 to the .NET Framework 3.0 Service Pack 1. Then, you change the input language in a text box on the Microsoft Expression Design surface to an East Asian language. In this scenario, the language does not function correctly.

Note: This problem also occurs on computers that have the Microsoft .NET Framework 3.5 installed.

When you perform an unattend installation of East Asian language versions of Windows Vista, the installation is not successful. Additionally, you receive the following error message:

Setup could not set display language

Note: This problem has been verified in the Japanese, Chinese (Taiwan), and Chinese (PRC) versions of Windows Vista. The problem does not occur in the Korean version of Windows Vista.

When you print a document that contains both vertical fonts and non-vertical fonts in Windows Vista, the document does not print correctly on a PostScript printer. For example, some printed characters may be broken up.

Note: A vertical font is designated with an “at” character (@) as the first character of its name. Vertical fonts are typically used on Asian systems.

On a Windows Vista-based computer, you cannot find the shortcut for the Private Character Editor (Eudcedit.exe) on the Start menu. However, you can still start the Private Character Editor by using the following command:
%systemroot%\system32\eudcedit.exe
Note The shortcut for the Private Character Editor appears on the Start menu in the East Asian language versions of Microsoft Windows XP, of Microsoft Windows 2000, and of Microsoft Windows NT 4.0.

When you start Windows Vista in safe mode and then log on to the computer, you cannot type any characters in an East Asian language.

Additionally, the language bar does not appear. Therefore, you cannot modify the language selection.
