	The Red Book says that the Encoding vector is a required item for
all fonts.  Why?  Is there some bit of internal PS font machinery that uses
it?  As far as I can tell, it's only used by the font-supplied BuildChar
routine.  What if I wanted to write a font in which there really wasn't any
reason to use the Encoding vector at all?  Maybe what I wanted to do was
have a font in which each character was simply a circle of thickness 30 and
radius c, centered in a 1000 unit square space, where c is the ascii code
for the character?  No reason for an Encoding vector, just:

	/BuildChar {
		1000 0 setcharwidth
		exch begin
		newpath 30 setlinewidth
		500 exch 500 exch 0 360 arc stroke
	} def

	Why wouldn't that work, other than the fact that definefont would
complain that there was an Encoding key-value pair missing?
