I'm using boost::serialization with QString, and I'm having the same problem as this poster: http://lists.boost.org/boost-users/2006/10/22940.php boost::serialization doesn't deal ideally with non-std::strings, and there are enough of them in use, that it is important (QString, CString, wxString, etc).

Would it be possible to add a mechanism that would make it easy to extend boost::serialization to handle new string types as conveniently as std::string/std::wstring?

I'm currently using the following helper-function to do the job, but ideally I'd want the same syntax for serializing QStrings as other strings.

template<class Archive> inline void serializeQString(Archive &ar, const char *name, QString &s) { if (Archive::is_saving::value) { std::string tmp(s.toUtf8().constData()); ar & boost::serialization::make_nvp(name, tmp); } else if (Archive::is_loading::value) { std::string tmp; ar & boost::serialization::make_nvp(name, tmp); s = QString::fromUtf8(tmp.c_str()); } }
