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. Therefore
a #define is required to use them.
To use non-const std::wstring references use the following %apply. Note
that they are passed by value.
%apply const std::wstring & {std::wstring &};
