Should there?

     std::string  a;
     std::wstring b( a.begin(),a.end());
     std::string  c(b.begin(),b.end());

All string algorithms in Boost are templates so they should work fine
with both std::string and std::wstring.

I think the real question is whether the OP was hoping for Unicode conversions of some kind in the process. ie what 'type' (sematically) are the wchar_t's and char's? UTF16? UTF32? (what size is the wchar_t?) etc.

Also, does the last line:
std::string c(b.begin(), b.end())

give at least a compiler warning about downconverting from wchar_t to char, and thus losing bits? (Which would be a hint that maybe you need some Unicode conversion or something else.)
