Including special characters in the message text

The \ (backslash) can be used to insert special characters into the message text.

These special characters are as follows:

\n
Inserts a new-line character.
\t
Inserts a horizontal tab character.
\v
Inserts a vertical tab character.
\b
Inserts a backspace character.
\r
Inserts a carriage-return character.
\f
Inserts a form-feed character.
\\
Inserts a backslash (\) character.
\ddd
Inserts a single-byte character associated with the octal value represented by the valid octal digits ddd.
Note: One, two, or three octal digits can be specified. However, you must include a leading zero if the characters following the octal digits are also valid octal digits. For example, the octal value for $ (dollar sign) is 44. To display $5.00, use \0445.00, and not \445.00, or the 5 will be parsed as part of the octal value.
\dd
Inserts a single-byte character associated with the hexadecimal value represented by the two valid hexadecimal digits dd. You must include a leading zero to avoid parsing errors (see the note about \ddd).
\dddd
Inserts a double-byte character associated with the hexadecimal value represented by the four valid hexadecimal digits dddd. You must include a leading zero to avoid parsing errors (see the note about \ddd).
