conversion of a single wchar_t with toupper

[kmw]

Hi,

I have no idea what I am doing wrong. The following piece of code
should work but it does not. Any ideas?

Output is:
T
T

#include <locale>
#include <string>

int main ( )
{
std::locale loc ( "en_US.UTF-8" );
//std::locale loc ( "de_DE.utf8" ); // I also tried this
std::wcout.imbue ( loc );
std::wcout << std::toupper<wchar_t> ( L't', loc ) << L'\n';
std::wcout << std::use_facet< std::ctype<wchar_t> >(loc).toupper
( L't' ) << L'\n';
std::wcout << std::toupper<wchar_t> ( L'ä', loc ) << L'\n';
std::wcout << std::use_facet< std::ctype<wchar_t> >(loc).toupper
( L'ä' ) << L'\n';
return 0;
}

Many thanks ind advance,
Kay

Define "should work".

OK, what was your *expected* output?

Please see FAQ 5.8.

Assuming you use g++ and you include iostream, the aswer is to add

std::ios_base::sync_with_stdio(false);

at the beginning of main.

Great! That does the trick. Many thanks.
