>Description:
std::wofstream::write( wchar_t*, n );

This function does not writes n elements of the wchar_t* string into the file. 
It writes n bytes of the wchar_t* string into the file.
>How-To-Repeat:
Simple compile the code with g++-3.0.3 and execute the program and then have a look at the created file "foobar".
On my system od says this:
$ od -c foobar
0000000   S  \0  \0  \0   h  \0  \0  \0   i  \0  \0
0000013

The string "Shithappens" won't be written completely as an UCS-4LE (on i386) string to the file. Only 11 bytes, thats the number of letters of the word "Shithappens", will be written to the file.
>Fix:
Workaround:
 wstring s = L"Shithappens";
 out.write( s.c_str(), s.size() * sizeof( wchar_t ) );
