well. I do not know weather or not the PostScript specification requests
that a fall back font is used when the font is not available. In case it
does not, it would be a permitted response to reject the EPS as invalid.

However since the author(s) of Ghostscript choose to use a fall back
font there is definitely a Bug in Ghostscript. Since the existents of
the pagul font disables this behavior.

That is only the place where the two errors become visible. The other
error is in Octave IMHO, since it also should not set an invalid font as
default. If it is allowed by the PostScript specification it would still
be not a good programming style.

Kind regards,

Hendrik
