I apologise to those who have no interest in Uniscribe, but I'm posting this question here because I know there are people on the list who know about Uniscribe, and I don't know of any other forum where I can ask questions about it.
We have an application that uses Uniscribe for text layout. It works fine on Windows XP Gold and SP1, using the versions of Uniscribe bundled with those OSs. When the application is run on XP SP2, justified text doesn't look right: letters overlap, for example.
Apparently this app uses a mix of Win32 calls and Uniscribe. I believe it measures text using a Win32 call, then uses that information to adjust the position of runs created with Uniscribe. I think it would be better to use Uniscribe consistently - but nonetheless, this approach worked with previous versions of Windows.
Are you aware of any change in Uniscribe in XP SP2 - of in the behaviour of the Win32 functions like GetTextExtent - that might account for this problem?
Thanks!
