/**
 * Function GetChars
 * returns a wxChar* to the actual wxChar* data within a wxString, and is
 * helpful for passing strings to wxString::Printf() and wxString::Format().
 * It can also be passed a UTF8 parameter which will be converted to wxString
 * by the compiler.
 * <p>
 * Example:  wxString::Format( wxT( "%s" ), GetChars( UTF( "some text" ) ) );
 * <p>
 * When wxWidgets is properly built for KiCad, a const wxChar* points to either:
 * <ul>
 * <li> 32 bit unicode characters on linux/OSX or </li>
 * <li> 16 bit UTF16 characters on windows. </li>
 * </ul>
 * Note that you cannot pass 8 bit strings to wxString::Format() or Printf() so this
 * is a useful conversion function to wxChar*, which is needed by wxString::Format().
 *
 * @return const wxChar* - a pointer to the UNICODE or UTF16 (on windows) text.
