Not "*", rather "*really broken-registry and charset", after someone had
done: 

  (set-charset-registries 'ascii ["really broken-registry and charset"])

Yes. Please post a bug report; I can?t reproduce--currently on Cygwin,
previously on NetBSD.

That wasn?t always the case; cf. the comment on x-init-device-faces in
x-faces.el.

Would you prefer a fallback to fixed for ASCII instead? XFree86 servers at
least give this error if it?s not available: 

Fatal server error:
could not open default font ?fixed?
