This is a little bit tricky.  Look carefully at the documentation regarding
BOOST_CLASS_IMPLEMENTATION and try replacing

BOOST_CLASS_IMPLEMENTATION(std::basic_string<unsigned char>, 
boost::serialization::primitive_type)
with
BOOST_CLASS_IMPLEMENTATION(std::basic_string<unsigned char>, 
boost::serialization::object_type)

(double check "object_type") Basically you want the next level of support 
above primitive_type.

Also, consider using

ar & static_cast<basic_string<char> >(my unsigned string)
