Special ASCII characters

Description

You can include special ASCII characters in strings. For example,
you might want to include a tab in a string to ensure proper spacing
or a bullet to indicate a list item. The tilde character (~) introduces
special characters. The tab is one of
the common ASCII characters that can be entered by typing a tilde
followed by a single keystroke. The bullet must be entered by typing
a tilde followed by the decimal, hexadecimal, or octal ASCII value
that represents it.
