58 applied to the text input. Newline characters are interpreted as record separators.
59 Backslash characters in the text will be interpreted in one of two ways: If the backslash
60 character precedes another backslash character, the pair will be interpreted as a literal

62 following the backslash will be interpreted as a hexadecimal specification of a single
63 character; for example, \\0a is a newline character in the ASCII character set.
65 For this reason, any backslash or newline characters that naturally occur in the text
66 input must be escaped to avoid misinterpretation by
