Boost::serialization with unicode values - REPOST

Hey guys,
I am new to boost. I have to work with boost::serialization.
My class is having a member that is wstring. This wstring may have unicode values
like

ഡഢണതഥദധന

[this is just some garbage I tried to test it with...]

When I try to add the unicode member to the xml_oarchive, it gives me the following assert

Quote:

Assertion failed!

Program: ...
File: [Some_Path]\Tools\Boost\.../mb_fro...har.hpp
Line: 93

Expression: -1 != m_bend

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts

Following is the code snippet... Help me guys, I am stuck :confused:

// Boost headers
#include "boost\archive\xml_oarchive.hpp"
#include "boost\serialization\list.hpp"
#include "boost\serialization\string.hpp"

std::stringstream StringStream;
boost::archive::xml_oarchive oa(StringStream, flags);
oa << boost::serialization::make_nvp("Tag", obj_with_wstring);

//Serialize method of the class with obj_with_wstring
serialize(Archive & ar, const unsigned int version)
{
     ar & boost::serialization::make_nvp("tag", m_wstrUnicode);	
}

I have posted the same question on discussion board too... Please excuse me for that...
