I think the actual problem is that he's trying to send an array
of wchar_t to the server.  That is not bit-compatible with UTF-8,
even though they are both representations of Unicode.  The query
string itself has the same problem I think (I believe the L"..."
syntax in C produces an array of wchar_t).
