* macros.h now has TO_UTF8() and FROM_UTF8() which are working converters
    to and from UTF-8 encoding for any wxWidgets build mode.  We can switch to
    them at any time.  I am using them now for specctra conversions and
    elsewhere where I wanted gauranteed UTF8 encoding.
  * added OUTPUTFORMATTER::Quoted( const wxString& ) to simplify converting
    to UTF8 encoded s-expression atoms.  The recommended technique is now simply:
        out->Quoted( wxString ).c_str()
