Hmmm. Perhaps then IsWindowUnicode doesn't work in Windows by checking
the window proc at all? MSDN doesn't mention such a thing.

Possibly the character set of the window is stored as an extra field in
the WND struct, and set manually by the window/dialog creation
functions. Would that be an acceptable way to implement this?
