Bug#128026: libstdc++3: std::wcout does not perform encoding conversions

[Martin von Loewis <loewis@informatik.hu-berlin.de>]

Package: libstdc++3
Version: 1:3.0.3-1
Severity: normal

Running the program

#include <iostream>

int main(){
	std::locale loc("de_DE.UTF-8");
	std::locale::global(loc);
	std::wcout<<L"Der \u20AC ist da"<<std::endl;
}

results in output that represents, in binary, as


0000000   D   e   r       ¬       i   s   t       d   a  \n  \0
          6544    2072    20ac    7369    2074    6164    000a
0000015

As you can see, the non-ASCII character U+20AC (EURO SIGN) was printed
as a two-byte value in what appears to be UCS-2. Instead, conversion
to UTF-8 should have been performed. This happens in every locale; try
de_DE.iso-8859-15 for another example (where EURO SIGN should have been
converted to a single byte, /xa4).
