       groff_char - groff glyph	names

       This  manual  page lists	the standard groff glyph names and the default
       input mapping, latin-1.	The glyphs in this document will look  differ-
       ent depending on	which output device was	chosen (with option -T for the
       man(1) program or the roff formatter).  Glyphs not  available  for  the
       device  that  is	 being	used to	print or view this manual page will be
       marked with `(N/A)'; the	device currently used is `ascii'.

       In the actual version, groff provides only 8-bit	characters for	direct
       input and named entities	for further glyphs.  On	ASCII platforms, input
       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 by
       default.	  This mapping is contained in the file	latin1.tmac and	can be
       changed by loading a different input encoding.  Note that some  of  the
       input  characters are reserved by groff,	either for internal use	or for
       special input purposes.	On EBCDIC platforms, only code page cp1047  is
       supported  (which  contains  the	 same characters as Latin-1; the input
       encoding	file is	called cp1047.tmac).  Again, some input	characters are
       reserved	 for internal and special purposes.  It	is rather straightfor-
       ward (for the experienced user) to set up other	8-bit  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 glyphs.   In  traditional
       roff  systems,  only names of length 2 were used, while groff also pro-
       vides support for longer	names.	It is  strongly	 suggested  that  only
       named  glyphs are used for all character	representations	outside	of the
       printable 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 and glyphs	can be
       tested positively with the `.if c' conditional.

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

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

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

       Input code
	      applies to glyphs	which can be input with	 a  single  character,
	      and  gives the ISO Latin-1 decimal code of that input character.
	      Note that	this code is equivalent	 to  the  lowest  256  Unicode
	      characters, including 7-bit ASCII	in the range 0 to 127.

       PostScript name
	      gives the	usual PostScript name of the glyph.

       Unicode decomposed
	      is the glyph name	used in	composite glyph	names.

   7-bit Character Codes 32-126
       These  are  the	basic  glyphs having 7-bit ASCII code values assigned.
       They are	identical to the printable characters of the  character	 stan-
       dards  ISO-8859-1  (Latin-1)  and  Unicode (range C0 Controls and Basic
       Latin).	The glyph names	used in	composite glyph	names are  `u0020'  up
       to `u007E'.

       Note  that input	characters in the range	0-31 and character 127 are not
       printable characters.  Most of them are invalid	input  characters  for
       groff anyway, and the valid ones	have special meaning.  For EBCDIC, the
       printable characters are	in the range 66-255.

       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).

       Most of the remaining characters	not in the just	described ranges print
       as themselves; the only exceptions are the following characters:

       `      the  ISO	Latin-1	 `Grave	 Accent' (code 96) prints as `,	a left
	      single quotation mark; the original character  can  be  obtained
	      with `\`'.

       '      the ISO Latin-1 `Apostrophe' (code 39) prints as ', a right sin-
	      gle quotation mark; the original character can be	obtained  with

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

       ~      the ISO Latin-1 `Tilde' (code 126) is  reduced  in  size	to  be
	      usable  as  a  diacritic;	 a  larger  glyph can be obtained with

       ^      the ISO Latin-1 `Circumflex Accent' (code	94) is reduced in size
	      to be usable as a	diacritic; a larger glyph can be obtained with

   8-bit Character Codes 160 to	255
       They are	interpreted as printable characters according to  the  Latin-1
       (iso-8859-1) code set, being identical to the Unicode range C1 Controls
       and Latin-1 Supplement.

       Input characters	in range 128-159 (on non-EBCDIC	hosts) are not	print-
       able characters.

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

       173    the soft hyphen control character.  groff	never uses this	 char-
	      acter  for  output  (thus	it is omitted in the table below); the
	      input character 173 is mapped onto `\%'.

       The remaining ranges (161-172, 174-255) are printable  characters  that
       print  as themselves.  Although they can	be specified directly with the
       keyboard	on systems with	a Latin-1 code page, it	is better to use their
       glyph names; see	next section.

   Named Glyphs
       Glyph names can be embedded into	the  document  text  by	 using	escape
       sequences.   groff(7) describes how these escape	sequences look.	 Glyph
       names can consist of quite  arbitrary  characters  from	the  ASCII  or
       Latin-1	code  set,  not	only alphanumeric characters.  Here some exam-

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

       \(ch   A	glyph having the 2-character name ch.

	      A	 glyph having the name char_name (having length	1, 2, 3, ...).

       \[base_glyph composite_1	composite_2 ...]
	      A	composite glyph; see below for a more detailed description.

       In groff, each 8-bit input character can	also referred to by  the  con-
       struct  `\[charn]' where	n is the decimal code of the character,	a num-
       ber between 0 and 255 without leading zeros  (those  entities  are  not
       glyph  names).	They  are  normally mapped onto	glyphs using the .trin
       request.	 Another special convention is the  handling  of  glyphs  with
       names  directly	derived	 from  a Unicode code point; this is discussed
       below.  Moreover, new glyph names can be	created	by the .char  request;
       see groff(7).

       In the following, a plus	sign in	the `Notes' column indicates that this
       particular glyph	name appears in	the PS version of the  original	 troff
       documentation, CSTR 54.

       The extensible bracket pieces are font-invariant	glyphs.	 In  classical
       troff  only  one	 glyph	was  available	to vertically extend brackets,
       braces, and parentheses:	`bv'.  We map it rather	arbitrarily to	u23AA.

       Note  that  not all devices contain extensible bracket pieces which can
       be piled	up with	`\b' due to the	restrictions of	 the  escape's	piling
       algorithm.   A  general solution	to build brackets out of pieces	is the
       following macro:

	      .\" Make a pile centered vertically 0.5em
	      .\" above	the baseline.
	      .\" The first argument is	placed at the top.
	      .\" The pile is returned in string `pile'
	      .de pile-make
	      .	 nr pile-wd 0
	      .	 nr pile-ht 0
	      .	 ds pile-args
	      .	 nr pile-# \n[.$]
	      .	 while \n[pile-#] \{\
	      .	   nr pile-wd (\n[pile-wd] >? \w'\$[\n[pile-#]]')
	      .	   nr pile-ht +(\n[rst]	- \n[rsb])
	      .	   as pile-args	\v'\n[rsb]u'\"
	      .	   as pile-args	\Z'\$[\n[pile-#]]'\"
	      .	   as pile-args	\v'-\n[rst]u'\"
	      .	   nr pile-# -1
	      .	 \}
	      .	 ds pile \v'(-0.5m + (\n[pile-ht]u / 2u))'\"
	      .	 as pile \*[pile-args]\"
	      .	 as pile \v'((\n[pile-ht]u / 2u) + 0.5m)'\"
	      .	 as pile \h'\n[pile-wd]u'\"

       Another complication is the  fact  that	some  glyphs  which  represent
       bracket	pieces	in  original  troff can	be used	for other mathematical
       symbols also, for example `lf' and `rf' which provide the `floor' oper-
       ator.   Other  devices  (most  notably for DVI output) don't unify such
       glyphs.	For this reason, the four glyphs `lf', `rf',  `lc',  and  `rc'
       are  not	unified	with similarly looking bracket pieces.	In groff, only
       glyphs with long	names are guaranteed to	 pile  up  correctly  for  all
       devices (provided those glyphs exist).

       The  font-invariant  glyphs `br', `ul', and `rn'	form corners; they can
       be used to build	boxes.	Note that both the PostScript and the Unicode-
       derived names of	these three glyphs are just rough approximations.

       `rn'  also serves in classical troff as the horizontal extension	of the
       square root sign.

       `ru' is a font-invariant	glyph, namely a	rule of	length 0.5m.

       Greek characters

       These glyphs are	intended for technical use, not	for real  Greek;  nor-
       mally, the uppercase letters have upright shape,	and the	lowercase ones
       are slanted.  There is a	problem	with the mapping of letter phi to Uni-
       code.   Prior  to  Unicode  version 3.0,	the difference between U+03C6,
       GREEK SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was  not  clearly
       described; only the glyph shapes	in the Unicode book could be used as a
       reference.  Starting with Unicode 3.0, the reference glyphs  have  been
       exchanged  and described	verbally also: In mathematical context,	U+03D5
       is the stroked variant and U+03C5 the curly glyph.  Unfortunately, most
       font vendors didn't update their	fonts to this (incompatible) change in
       Unicode.	 At the	time of	this writing (February 2003), it is not	 clear
       yet  whether  the  Adobe	 Glyph	Names `phi' and	`phi1' also change its
       meaning if used for mathematics,	thus compatibility problems are	likely
       to happen - being conservative, groff currently assumes that `phi' in a
       PostScript symbol font is the stroked version.

       In groff, symbol	`\[*f]'	always denotes the stroked version of phi, and
       `\[+f]' the curly variant.
