Comment (by nate@…):

 Perhaps one can look to the standard library for inspiration? In the
 `locale` header there is the
 [http://en.cppreference.com/w/cpp/locale/codecvt std::codecvt] class which
 can be used with [http://en.cppreference.com/w/cpp/locale/wstring_convert

 std::wstring_convert] to perform convertions from one encoding to another.

 Below is an example using the C++11 class
 [http://en.cppreference.com/w/cpp/locale/codecvt_utf8_utf16

 std::codecvt_utf8_utf16] to convert a UTF-16 `std::wstring` to a UTF-8
 encoded `std::string`. I am using this in my application to great success
 so far.

 {{{
     std::wstring wideString;
     std::wstring_convert<
         std::codecvt_utf8_utf16< std::wstring::value_type >,
         std::wstring::value_type
     > utf16conv;
     std::string narrowString = utf16conv.to_bytes( wideString );
 }}}

 I hope this helps to show a potential way to narrow characters.
