NetBSD 6.1.5 - man page for groff_char (netbsd section 7)

GROFF_CHAR(7)									    GROFF_CHAR(7)

       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 different 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  encod-
       ing  file  is called cp1047.tmac).  Again, some input characters are reserved for internal
       and special purposes.  It is rather straightforward (for the experienced user) to  set  up
       other  8-bit  encodings	like Latin-2; since groff will use Unicode in the next major ver-
       sion, 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 provides support for longer names.  It is
       strongly suggested that only named glyphs are used for all character representations  out-
       side 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  standards  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  charac-
       ters.  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 single quotation  mark;
	      the original character can be obtained with `\(aq'.

       -      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 `\(ti'.

       ^      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 `\(ha'.

   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 printable characters.

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

       173    the  soft  hyphen  control  character.   groff never uses 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) 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 examples:

       \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  construct  `\[charn]'
       where  n  is the decimal code of the character, a number 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 origi-
       nal troff can be used for other mathematical symbols also, for example `lf' and `rf' which
       provide	the  `floor'  operator.   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 guaran-
       teed 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; normally, the uppercase
       letters have upright shape, and the lowercase ones are slanted.	There is a  problem  with
       the  mapping  of  letter  phi  to  Unicode.   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.  Start-
       ing 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
