That's what you're using if you type

	xterm -fa Akkadian

bitmap fonts use a different (-fn) option.  However, xterm is translating
all of the above-0xffff values to the replacement character as it reads
them.  To change this, I'll have to undo that - but replace the check
with several other changes in the program to make bitmap fonts still work.
(I didn't do that this week since I was closing out changes for #230).
