Hi: 
What is the best way (in terms of efficiency) to convert an std::vector
of wchar_t to std::wstring.
I can think of a oupple of aproaches: 
1. using std::copy.
2. using boost::lexical_cast.
3 using boost::foreach
4. Usin he boost::serialization library.
The std::wstring doesn't ned to be output to a file.
Any advice apreciated.
Sean.
What about the sequence assignment capabilities of basic_string
itself, like this:

std::wstring from_vector(const std::vector<wchar_t>& src) {
   return std::wstring(src.begin(), src.end());
}

?

For already existing std::wstring objects you could use
it's assign overload that accepts an input iterator pair.
