how do I read unicode text files?

[Boris]

Hi,
I saved a notepad textfile with "unicode" coding and tried this code:

std::wifstream
in( "test.txt" );
assert( in );
in.unsetf( std::wios::skipws );

std::wstring
w = std::wstring( std::istream_iterator< wchar_t, wchar_t >( in ),
std::istream_iterator< wchar_t, wchar_t >());
std::wcout << w << std::endl;

Unfortunatly I get

 ■t e s t u n i c o d e

instead of

test unicode

I like to get rid of the redundant spaces and the control charakter at the
beginning. When I do this for "ANSI" encoding, everything is ok.
Can anybody help?

Thanks,

Boris
