I think that was sheer luck (and probably the way how wxString is
internally represented).

I wouldn't say it's a bug. The ellipsis operator used in
wxString::Format() IMHO behaves the same as in sprintf(), if you run

std::string s("Hello World");
char sz[100];
sprintf(sz, "%s", s);

you cannot be sure what you get. So either you use .c_str() or cast it
to wxChar - whatever you like better.

2ct,
Volker
