Have you tried handling WM_UNICHAR instead of tricking the VM into 
Unicode mode? If you do what you did above some other messages come in 
with Unicode args too and while this may be desirable at some point I'm 
not sure if we want this right away. For the time being I'd feel safer 
if we would handle WM_UNICHAR explicitly. Also, WM_UNICHAR uses 
(according to the docs) UTF-32 instead of UTF-16 as in your code. This 
might come in handy at some point.

I'm happy to fold the fixes into the mainstream version.
