I agree with Octavian, we don't want to rely on heuristics. Alexandre
has rejected proposals based on IsTextUnicode before.

I found this bit on MSDN:
(http://msdn.microsoft.com/en-us/library/ms997515.aspx)

> Working with Unicode in Windows NT
> 
> Applications that register a DDE window class that is Unicode must use Unicode
> execute strings when communicating with other Unicode DDE windows. They must
> use ASCII (OEM codepage) execute strings when communicating with non-Unicode
> DDE windows. Any window's state can be determined by calling IsWindowUnicode.
> This convention places the burden of backward compatibility on Unicode DDE
> applications.

> Unicode compatibility is only a problem for raw DDE applications because DDEML

I guess we should find out how Internet Explorer behaves when you use raw DDE.
