Comment (by neverpanic):

 I think the problem may be that iconv is used for character set conversion
 from a `std::wstring`'s internal memory representation and iconv assumes
 what the actual encoding is (despite the C++ standard not specifying one).
 Here's a minimal reproducer:

 {{{
 #!cpp
 /* clang++ -std=c++11 -Wall -Werror $(pkg-config --cflags --libs
 glibmm-2.4) test.cpp -o test */
 #include <glibmm.h>
 #include <iostream>
 #include <string>

 int main() {
         std::wstring str = L"Fööööö";
         GError* error = nullptr;
         gsize n_bytes;
         const auto buf = g_convert(reinterpret_cast<const
 char*>(str.data()), str.size() * sizeof(std::wstring::value_type),
 "UTF-8", "WCHAR_T", nullptr, &n_bytes, &error);

         if (error) {
                 std::cout << error->message << std::endl;
         } else {
                 std::cout << buf << std::endl;
         }
 }
 }}}
