/* X_string is a null-terminated string in the X charset whose
   elements are as follows.  X should be the name the `set charset'
   command uses for the character set, in lower-case, with any
   non-identifier characters replaced with underscores.  Where a
   character set doesn't have the given character, the string should
   contain the character 'x'.

   [0] --- the `alert' character, '\a'
   [1] --- the `backspace' character, '\b'
   [2] --- the `escape' character, '\e'
   [3] --- the `form feed' character, '\f'
   [4] --- the `line feed' character, '\n'
   [5] --- the `carriage return' character, '\r'
   [6] --- the `horizontal tab' character, '\t'
   [7] --- the `vertical tab' character, '\v'
   [8  .. 33] --- the uppercase letters A-Z
   [34 .. 59] --- the lowercase letters a-z
   [60 .. 69] --- the digits 0-9
   [70] --- the `cent' character
   [71] --- a control character with no defined backslash escape

   Feel free to extend these as you like.  */
