/**
* Function GetChars
* returns a wxChar* to the actual character data within a wxString, and is
* helpful for passing strings to wxString::Printf(wxT("%s"), GetChars(wxString) )
* <p>
* wxChar is defined to be
* <ul>
* <li> standard C style char when wxUSE_UNICODE==0 </li>
* <li> wchar_t when wxUSE_UNICODE==1 (the default). </li>
* </ul>
* i.e. it depends on how the wxWidgets library was compiled. There was a period
* during the development of wxWidgets 2.9 when GetData() was missing, so this
* function was used to provide insulation from that design change. It may
* no longer be needed, and is harmless. GetData() seems to be an acceptable
* alternative in all cases now.
