+Finally notice that each of the parsing functions is available in several
+overloads: if the input string is a narrow (\texttt{char *}) string, then a
+narrow pointer is returned. If the input string is a wide string, a wide char
+pointer is returned. Finally, if the input parameter is a wxString, a narrow
+char pointer is also returned for backwards compatibility but there is also an
+additional argument of wxString::const\_iterator type in which, if it is not
+\NULL, an iterator pointing to the end of the scanned string part is returned.
