29/* X_string is a null-terminated string in the X charset whose
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
