Comment (by kencu):

 This little test:
 {{{
 #include<iostream>
 #include<string>

 int main ()
 {
   char16_t x[] = { 'a', 'b', 'c', 0 };
   std::u16string arr = x;

   std::cout << "arr.length = " << arr.length() << std::endl;
   for(auto i : arr)
     std::cout << i << "\n";
 }
 }}}
 seems to compile with no troubles with these build lines, so ... ?
 {{{
 clang++ -std=c++11 -stdlib=macports-libstdc++ -c test.cpp
 clang++ -std=c++11 -D_GLIBCXX_USE_CXX11_ABI=0 -stdlib=macports-libstdc++
 -c test.cpp
 clang++ -std=c++1z -D_GLIBCXX_USE_CXX11_ABI=0 -stdlib=macports-libstdc++
 -c test.cpp
 }}}
