 CharSet.Auto,    ExactSpelling = true -> FormatMessageW
 The latter doesn't make much sense, but it works, though.
 I don't see a bug here.

+Robert, I thought the mangling issue was there when exactspelling was 
+false (not true). You probably just made a typo, as the results you 
+get match those you get when ExactSpelling is false. With 
+ExactSpelling set to true you would have gotten an 
+EntryPointNotFoundException in all three cases (on both Mono and 
+You would not have seen the "problem" I described when pinvoking 
+FormatMessage, as there's no plain FormatMessage entrypoint (it has 
+only Ansi and Unicode versions).
+However, after looking close at the MS docs I noticed that there was 
+indeed a difference between name mangling for Unicode and Ansi which 
+matches the Mono behavior .... For Ansi, it should first search for 
+the unmangled name, while for Unicode it should first probe for the 
+mangled name ... Sorry for the bogus report ...
