GROFF_CHAR(7)	       Miscellaneous Information Manual		 GROFF_CHAR(7)

NAME
       groff_char - groff character names

DESCRIPTION
       This manual page	lists the standard groff input characters.  The	output
       characters in this document will	look different depending on which out-
       put  device  was	 chosen	 (with option -T for the man(1)	program	or the
       roff formatter).	 Only the characters that are available	for the	device
       that  is	being used to print or view this manual	page will be displayed
       (the device currently used is `ascii').

       In the actual version, groff provides only 8-bit	characters for	direct
       input  and  named  characters  for further glyphs.  On ASCII platforms,
       character codes in the range 0 to 127  (decimal)	 represent  the	 usual
       7-bit ASCII characters, while codes between 127 and 255 are interpreted
       as the corresponding characters in the Latin-1 (ISO-8859-1)  code  set.
       On EBCDIC platforms, only the code page cp1047 is supported (which con-
       tains the same characters as Latin-1).  It  is  rather  straightforward
       (for the	experienced user) to set up other 8bit encodings like Latin-2;
       since groff will	use Unicode in the next	major version,	no  additional
       encodings are provided.

       All  roff  systems  provide the concept of named	characters.  In	tradi-
       tional roff systems, only names of length 2 were	used, while groff also
       provides	 support for longer names.  It is strongly suggested that only
       named characters	are used for all characters outside of the 7-bit ASCII
       range.

       Some  of	the predefined groff escape sequences (with names of length 1)
       also produce single characters; these exist for historical  reasons  or
       are printable versions of syntactical characters.  They include \\, \',
       \`, \-, \., and \e; see groff(7).

       In groff, all of	these different	types of characters can	be tested pos-
       itively with the	.if c conditional.

REFERENCE
       In this section,	the characters in groff	are specified in tabular form.
       The meaning of the columns is as	follows.

       Output shows how	the character is printed for the current  device;  al-
	      though  this  can	have quite a different shape on	other devices,
	      it always	represents the same glyph.

       Input name
	      specifies	how the	character is input either directly by a	key on
	      the keyboard, or by a groff escape sequence.

       Input code
	      applies  to  characters which can	be input with a	single charac-
	      ter, and gives the ISO Latin-1 decimal code of that input	 char-
	      acter.  Note that	this code is equivalent	to the lowest 256 Uni-
	      code characters; (including 7-bit	ASCII in the range 0 to	127).

       PostScript name
	      gives the	usual PostScript name of the output character.

   ASCII Characters
       These are the basic characters having 7-bit ASCII code  values.	 These
       are  identical  to  the first 127 characters of the character standards
       ISO-8859-1 (Latin-1) and	Unicode	(range C0 Controls and	Basic  Latin).
       To save space, not every	code has an entry in the following because the
       following code ranges are well known.

       0-32   Control characters (print	as themselves).

       48-57  Decimal digits 0 to 9 (print as themselves).

       65-90  Upper case letters A-Z (print as themselves).

       97-122 Lower case letters a-z (print as themselves).

       127    Control character	(prints	as itself).

       The remaining ranges constitute the printable,  non-alphanumeric	 ASCII
       characters;  only  these	are listed below.  As can be seen in the table
       below, most of these characters print as	themselves;  the  only	excep-
       tions are the following characters:

       `      the  ISO	Latin-1	 `Grave	 Accent' (code 96) prints as `,	a left
	      single quotation mark,

       '      the ISO Latin-1 `Apostrophe' (code 39) prints as ', a right sin-
	      gle quotation mark; the corresponding ISO	Latin-1	characters can
	      be obtained with \` and \(aq.

       -      the ISO Latin-1 `Hyphen, Minus Sign' (code 45) prints as	a  hy-
	      phen; a minus sign can be	obtained with \-.

       ~      the  ISO	Latin-1	 `Tilde' (code 126); a larger glyph can	be ob-
	      tained with \(ti.

       ^      the ISO Latin-1 `Circumflex Accent' (code	94);  a	 larger	 glyph
	      can be obtained with \(ha.

   Latin-1 Special Characters
       These  characters  have	character codes	between	128 and	255.  They are
       interpreted as characters according to the  Latin-1  (iso-8859-1)  code
       set,  being identical to	the Unicode range C1 Controls and Latin-1 Sup-
       plement.

       128-159
	      the C1 Controls; they print as themselves,  but  the  effect  is
	      mostly undefined.

       160    the  ISO	Latin-1	 no-break space	is mapped to `\	', the escaped
	      space character.

       173    the soft hyphen control character	 (prints  as  itself).	 groff
	      never  use  this character for output (thus it is	omitted	in the
	      table below); the	input character	173 is mapped onto \%.

       The remaining ranges (161-172, 174-255),	called the Latin-1  Supplement
       in  Unicode,  are  printable  characters	that print as themselves.  Al-
       though they can be specified directly with the keyboard on systems with
       a  Latin-1 code page, it	is better to use their named character equiva-
       lent; see next section.

   Named Characters
       The named character idiom is the	standard way to	specify	special	 char-
       acters in roff systems.	They can be embedded into the document text by
       using escape sequences.	groff(7) describes how these escape  sequences
       look.   The  character  names can consist of quite arbitrary characters
       from the	ASCII or Latin-1 code set, not only  alphanumeric  characters.
       Here some examples:

       \c     named  character	having	the name c, which consists of a	single
	      character	(length	1).

       \(ch   named character having the 2-character name ch.

       \[char_name]
	      named character having the name char_name	(having	length	1,  2,
	      3, ...).

       In  groff,  each	 8bit input character can also referred	to by the con-
       struct \n[charn]	where n	is the decimal code of the character, a	number
       between	0  and 255  without leading zeros.  They are mapped onto glyph
       entities	using the .trin	request.  Moreover, new	character names	can be
       created by the .char request; see groff(7).
