Consider the following scenario:
- You are running a Windows XP-based computer.
- You create an End User Defined Character (EUDC) font.
- You deploy the EUDC font to a Windows Vista-based computer or to a Windows Server 2008-based computer.
In this scenario, you cannot enter the EUDC characters by using the Pinyin (phonetic) Input Method Editor (IME) or the Changjie IME.
This issue also occurs if you upgrade a Windows XP-based computer to Windows Vista.
