SYMPTOMS
You run an application on a Microsoft Windows XP Service Pack 2 (SP2)-based computer. In the application, you call the GetCharacterPlacement function to retrieve information about a character string. The character string uses a font that has the OpenType font format. When you call the GetCharacterPlacement function for the first time, the function unexpectedly returns zero. When you call the GetCharacterPlacement function again, you receive an access violation. However, when you run the application on a Windows XP Service Pack 1 (SP1)-based computer, the GetCharacterPlacement function returns the correct value.
