Hi Jeff- The underscore is a macro to call wxGetTranslation(). There's some null checking there but more importantly, it returns a wxString that will be valid regardless of the the contents. If you cast a wxString with no data to a C string, you still get the valid pointer to the data segment (just has length 0).
