DdeInitialize determines the default codepage but the app can override it
via the iCodePage field of the CONVCONTEXT structure. Changing the call
to DdeInitializeA breaks other apps, see bug 13740 for example.

We need a way to retrieve the codepage from the conversation handle.
That and a patch like the one from comment #1 would fix this bug I believe.
