ANSI Common Lisp   13 Characters   13.1 Character Concepts

13.1.7 Character Names

• Newline

  The character that represents the division between lines. An implementation must translate between #\Newline, a single-character representation, and whatever external representation(s) may be used.

• Space

  The space or blank character.

The following names are semi-standard; if an implementation supports them, they should be used for the described characters and no others.

• Rubout

  The rubout or delete character.

• Page

  The form-feed or page-separator character.

• Tab

  The tabulate character.

• Backspace

  The backspace character.

• Return

  The carriage return character.

• Linefeed

  The line-feed character.

In some implementations, one or more of these character names might denote a standard character; for example, #\Linefeed and #\Newline might be the same character in some implementations.
