  71 ;;   DOS display setup
  72 ;;   =================
  73 ;;
  74 ;;   DOS can only support a single font.  On most systems (with the
  75 ;;   possible exception of Far Eastern DOS versions), this means that
  76 ;;   two character sets are available at any given time: the ASCII
  77 ;;   charset, and a single national charset, usually mapped to codes
  78 ;;   above 128 (i.e., with 8th bit set).  Which national charset is
  79 ;;   supported depends on the codepage loaded by the system when it
  80 ;;   boots; usually, this codepage cannot be changed without
  81 ;;   rebooting.
  82 ;;
  83 ;;   Since each codepage can usually display character of a single
  84 ;;   MULE charset, Emacs can display a single MULE charset with the
  85 ;;   glyphs of the current codepage.  When Emacs starts on DOS, it
  86 ;;   automatically sets its default coding systems for file I/O and
  87 ;;   terminal output according to the currend DOS codepage, given by
  88 ;;   the `dos-codepage' variable.
  89 ;;
  90 ;;   This leaves us with the problem of displaying character sets
  91 ;;   other than the one which maps directly into the current codepage.
  92 ;;   The following functions and variables handle this nuisance by
  93 ;;   defining a display table where each character that doesn't have a
  94 ;;   glyph in some codepage is mapped to a string which represents it.
  95 ;;   For example, a small c with cedilla is mapped to the string
  96 ;;   ",c".  A nice feature of the display tables is that Emacs
  97 ;;   knows that the string represents a single character, and thus
  98 ;;   cursor motion works as you'd expect: a single `C-f' moves past
  99 ;;   the entire string which represents a single character.
