So, there is problem in toUTF8 in std.utf "toUTF8(in wchar[] s)".
string cwd()// copied from phobos
{
writeln("start");
import core.sys.windows.windows;
writeln("buff");
wchar[] ret = new wchar[10240];
writeln("call");
auto n = GetCurrentDirectoryW(to!DWORD(ret.length), ret.ptr);
writeln("return");
return ret[0 .. n].to!string();
}
Works as expected on both win32 and win64.
