You can't do that. lexical_cast from X to Y requires that there is a stream to 
which X can be written and from which Y can be read. However, string can only be 
read from basic_stream<char> and wstring can only be written to 
basic_stream<wchar_t>.

However, if you add an operator that can read a wstring from a stream<char>, and 
one that can read a string from a stream<wchar_t>, then it will work.
