My simplest way to show the bug yet:

(list
 (unencodable-char-position 0 5 'iso-latin-1-unix 1 "100 Ω")
 (progn (apply 'set-charset-priority (charset-priority-list))
	(unencodable-char-position 0 5 'iso-latin-1-unix 1 "100 Ω"))
 (progn (apply 'set-charset-priority (list (charset-priority-list t)))
	(unencodable-char-position 0 5 'iso-latin-1-unix 1 "100 Ω")))
=> ((4) nil (4)) ; the middle nil is wrong

I am submitting a bug report.
