  30    elements are as follows.  X should be the name the `set charset'
  31    command uses for the character set, in lower-case, with any
  32    non-identifier characters replaced with underscores.  Where a
  33    character set doesn't have the given character, the string should
  34    contain the character 'x'.
  35
  36    [0] --- the `alert' character, '\a'
  37    [1] --- the `backspace' character, '\b'
  38    [2] --- the `form feed' character, '\f'
  39    [3] --- the `line feed' character, '\n'
  40    [4] --- the `carriage return' character, '\r'
  41    [5] --- the `horizontal tab' character, '\t'
  42    [6] --- the `vertical tab' character, '\v'
  43    [7  .. 32] --- the uppercase letters A-Z
  44    [33 .. 58] --- the lowercase letters a-z
  45    [59 .. 68] --- the digits 0-9
  46    [69] --- the `cent' character
  47    [70] --- a control character with no defined backslash escape
