13.1.7 Character Names

The following character names must be present in all conforming implementations:

  • 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.
