+ * Typemaps for std::wstring and const std::wstring&
+ *
+ * These are mapped to a Java String and are passed around by value.
+ * Warning: Unicode / multibyte characters are handled differently on different 
+ * OSs so the std::wstring typemaps may not always work as intended.
+ *
+ * To use non-const std::wstring references use the following %apply.  Note 
+ * that they are passed by value.
+ * %apply const std::wstring & {std::wstring &};
