2.2 Representation of Characters
This section briefly discusses how characters are represented in Emacs
buffers. Note: Key Sequences, for information on representing key
sequences to create key bindings.
ASCII graphic characters in Emacs buffers are displayed with their
graphics. <LFD> is the same as a newline character; it is displayed by
starting a new line. <TAB> is displayed by moving to the next tab stop
column (usually every 8 spaces). Other control characters are
displayed as a caret (`^') followed by the non-control version of the
character; thus, `C-a' is displayed as `^A'. Non-ASCII characters 128
and up are displayed with octal escape sequences; thus, character code
243 (octal), also called `M-#' when used as an input character, is
displayed as `\243'.
The variable `ctl-arrow' may be used to alter this behavior. Note:
