To activate the fill-column indication display, use the minor modes
-@w{@kbd{M-x display-fill-column-indicator-mode}} and
-@w{@kbd{M-x global-display-fill-column-indicator-mode}}, which enable
+@kbd{M-x display-fill-@-column-indicator-mode} and
+@kbd{M-x global-display-fill-column-indicator-mode}, which enable
the indicator locally or globally, respectively.
Alternatively, you can set the two buffer-local variables
through the functions @code{display-fill-column-indicator-mode} or
@code{global-display-fill-column-indicator-mode}, they will use the
character specified by this variable, if it is non-@code{nil};
-otherwise Emacs will use the character @samp{U+2502 VERTICAL LINE},
-falling back to @samp{|} if @code{U+2502} cannot be displayed.

@cindex control characters on display
The @acronym{ASCII} character set contains non-printing @dfn{control
characters}. Two of these are displayed specially: the newline
-character (Unicode code point @code{U+000A}) is displayed by starting
-a new line, while the tab character (@code{U+0009}) is displayed as a
+character (Unicode code point U+000A) is displayed by starting
+a new line, while the tab character (U+0009) is displayed as a
space that extends to the next tab stop column (normally every 8
columns). The number of spaces per tab is controlled by the
buffer-local variable @code{tab-width}, which must have an integer
definition of @key{TAB} as a command.
Other @acronym{ASCII} control characters, whose codes are below
-@code{U+0020} (octal 40, decimal 32), are displayed as a caret
+U+0020 (octal 40, decimal 32), are displayed as a caret
(@samp{^}) followed by the non-control version of the character, with
the @code{escape-glyph} face. For instance, the @samp{control-A}
-character, @code{U+0001}, is displayed as @samp{^A}.
+character, U+0001, is displayed as @samp{^A}.

+ The raw bytes with codes U+0080 (octal 200) through
+U+009F (octal 237) are displayed as @dfn{octal escape

If you change the buffer-local variable @code{ctl-arrow} to
@code{nil}, the @acronym{ASCII} control characters are also displayed
as octal escape sequences instead of caret escape sequences. (You can
realization, e.g., by yanking; for instance, source code compilers
typically do not treat non-@acronym{ASCII} spaces as whitespace
characters. To deal with this problem, Emacs displays such characters
-specially: it displays @code{U+00A0} (no-break space) and other
+specially: it displays U+00A0 @sc{no-break space} and other
characters from the Unicode horizontal space class with the

-hyphen) with the @code{nobreak-hyphen} face. To disable this, change
+@code{nobreak-space} face, and it displays U+00AD @sc{soft
+hyphen}, U+2010 @sc{hyphen}, and U+2011 @sc{non-breaking
+hyphen} with the @code{nobreak-hyphen} face. To disable this, change
the variable @code{nobreak-char-display} to @code{nil}. If you give
this variable a non-@code{nil} and non-@code{t} value, Emacs instead
displays such characters as a highlighted backslash followed by a
That produces incorrect results when CJK and Latin text are mixed
together (because CJK characters don't use whitespace to separate
words). You can customize the option @code{word-wrap-by-category} to
-allow Emacs to break lines after any character with ``|'' category
+allow Emacs to break lines after any character with @samp{|} category
(@pxref{Categories,,, elisp, the Emacs Lisp Reference Manual}), which
provides better support for CJK characters. Also, if this variable is
set using Customize, Emacs automatically loads @file{kinsoku.el}.
When @file{kinsoku.el} is loaded, Emacs respects kinsoku rules when
-breaking lines. That means characters with the ``>'' category don't
-appear at the beginning of a line (e.g., U+FF0C FULLWIDTH COMMA), and
-characters with the ``<'' category don't appear at the end of a line
-(e.g., U+300A LEFT DOUBLE ANGLE BRACKET). You can view the category
+breaking lines. That means characters with the @samp{>} category don't
+appear at the beginning of a line (e.g., U+FF0C @sc{fullwidth comma}), and
+characters with the @samp{<} category don't appear at the end of a line
+(e.g., U+300A @sc{left double angle bracket}). You can view the category
set of a character using the commands @code{char-category-set} and
@code{category-set-mnemonics}, or by typing @kbd{C-u C-x =} with point
on the character and looking at the ``category'' section in the
