- ASCII graphic characters in Emacs buffers are displayed with their
-graphics. ＠key{LFD} is the same as a newline character; it is displayed
-by starting a new line. ＠key{TAB} is displayed by moving to the next
-tab stop column (usually every 8 spaces). Other control characters are
-displayed as a caret (＠samp{^}) followed by the non-control version of
-the character; thus, ＠kbd{C-a} is displayed as ＠samp{^A}. Non-ASCII
-characters 128 and up are displayed with octal escape sequences; thus,
-character code 243 (octal), also called ＠kbd{M-#} when used as an input
-character, is displayed as ＠samp{\243}.
+ Printable characters (letters, numbers, punctuation and so on) in
+XEmacs buffers are displayed as such. ＠key{LFD} (line feed, character
+code ＠samp{\012} (octal)) is the same as a newline character; it is
+displayed by starting a new line. ＠key{TAB} is displayed by moving to
+the next tab stop column (usually every 8 spaces). Other control
+characters below #x20 (hexadecimal) are displayed as a caret (＠samp{^})
+followed by the non-control version of the character; thus, ＠kbd{C-a} is
+displayed as ＠samp{^A}. Characters between (hexadecimal) #x80 and #xA0
+are displayed with octal escape sequences; thus, character code 243
+(octal), also called ＠kbd{M-#} when used as an input character, is
+displayed as ＠samp{\243}.
The variable ＠code{ctl-arrow} may be used to alter this behavior.

+＠xref{Display Vars}. As a rule, its value limits octal display to those
+characters in the range just mentioned, and otherwise characters are
+treated as printable, and will be displayed as themselves when the
+relevant fonts are available.
