boost::program_options::value_semantic_codecvt_helper<wchar_t>
// In header: <boost/program_options/value_semantic.hpp> class value_semantic_codecvt_helper<> : public { public: // private member functions (, , ) ; // protected member functions (, ) ; };
Helper conversion class for values that accept ascii strings as input. Overrides the 'parse' method and defines new 'xparse' method taking std::wstring. Depending on whether input to parse is ascii or UTF8, will recode input to Unicode, or pass it unmodified.
