That's easy, any *non-digit* character can be escaped with a preceding
"\", or alternatively as a 3-digit *decimal* \DDD sequence.
The text in 1035 is:
\X where X is any character other than a digit (0-9), is
used to quote that character so that its special meaning
does not apply. For example, "\." can be used to place
a dot character in a label.
\DDD where each D is a digit is the octet corresponding to
the decimal number described by DDD. The resulting
octet is assumed to be text and is not checked for
