;; The Tar data is made up of bytes and better manipulated as bytes
;; and can be very large, so insert/delete can be costly. The summary we
-;; want to display may contain non-ascci chars, of course, so we'd like it
+;; want to display may contain non-ascii chars, of course, so we'd like it
;; to be multibyte. We used to keep both in the same buffer and switch
;; from/to uni/multibyte. But this had several downsides:
;; - set-buffer-multibyte has an O(N^2) worst case that tends to be triggered
