23 ;;; Commentary:
25 ;; This package sets up display of ISO 8859-n for n>1 by substituting
26 ;; Latin-1 characters and sequences of them for characters which can't
27 ;; be displayed, either because we're on a tty or because we don't
28 ;; have the relevant window system fonts available. For instance,
29 ;; Latin-9 is very similar to Latin-1, so we can display most Latin-9
30 ;; characters using the Latin-1 characters at the same code point and
31 ;; fall back on more-or-less mnemonic ASCII sequences for the rest.
33 ;; For the Latin charsets the ASCII sequences are mostly consistent
34 ;; with the Quail prefix input sequences. Latin-4 uses the Quail
35 ;; postfix sequences since a prefix method isn't defined for Latin-4.
37 ;; [A different approach is taken in the DOS display tables in
38 ;; term/internal.el, and the relevant ASCII sequences from there are
39 ;; available as an alternative; see `latin1-display-mnemonic'. Only
40 ;; these sequences are used for Arabic, Cyrillic, Greek and Hebrew.]
42 ;; If you don't even have Latin-1, see iso-ascii.el and use the
43 ;; complete tables from internal.el. The ASCII sequences used here
44 ;; are mostly in the same style as iso-ascii.

48 ;; Ensure `standard-display-table' is set up:

77 ASCII sequences are used, mostly following the Latin prefix input
78 methods. Some different ASCII sequences are used if
