indicate that the string continues on the following line. The backslash and the
end-of-line marker following it are not considered part of the string. For example:

   ( These \
   two strings \
   are the same . )
   ( These two strings are the same . )

If an end-of-line marker appears within a literal string without a preceding
backslash, the result is equivalent to \n (regardless of whether the end-of-line
marker was a carriage return, a line feed, or both). For example:

   ( This string has an end−of−line at the end of it .
   )
   ( So does this one .\n )

The \ddd escape sequence provides a way to represent characters outside the
printable ASCII character set. For example:

   ( This string contains \245two octal characters\307 . )

The number ddd may consist of one, two, or three octal digits, with high-order
overflow ignored. It is required that three octal digits be used, with leading zeros
as needed, if the next character of the string is also a digit. For example, the literal

   ( \0053 )

denotes a string containing two characters, \005 (Control-E) followed by the digit
3, whereas both

   ( \053 )

and

   ( \53 )

denote strings containing the single character \053, a plus sign (+).

This notation provides a way to specify characters outside the 7-bit ASCII
character set by using ASCII characters only. However, any 8-bit value may
appear in a string. In particular, when a document is encrypted (see Section 3.5,
“Encryption”), all of its strings are encrypted and often contain arbitrary 8-bit
