       groff_char - groff glyph names


       This  manual  page lists the standard groff glyph names and the default
       input mapping, latin1.  The glyphs  in  this  document  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 are 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 latin1 (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 latin1; the input
       encoding file is called cp1047.tmac).  Again, some input characters are
       reserved for internal and special purposes.

       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 outside of  the
       printable 7-bit ASCII range.

       Some  of the predefined groff escape sequences (with names of length 1)
       also produce single glyphs; 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 latin1 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 (latin1) and Unicode  (range  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  latin1  `Grave  Accent'  (code 96) prints as `, a left
              single quotation mark; the original character  can  be  obtained
              with `\`'.

       '      the  ISO  latin1  `Apostrophe'  (code 39)  prints  as ', a right
              single quotation mark; the original character  can  be  obtained
              with `\(aq'.

       -      the  ISO  latin1  `Hyphen,  Minus  Sign'  (code 45)  prints as a
              hyphen; a minus sign can be obtained with `\-'.

       ~      the ISO latin1 `Tilde' (code 126)  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  latin1
       (ISO-8859-1)  code  set,  being  identical to the Unicode range Latin-1

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

       160    the ISO latin1 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 latin1 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
       latin1 code set, not only alphanumeric characters.  Here some examples:

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

              A  glyph having the name char_name (having length 1, 2, 3, ...).
              Note that `c' is not the same as `\[c]' (c a single  character):
              The latter is internally mapped to glyph name `\c'.  By default,
              groff defines a single glyph name  starting  with  a  backslash,
              namely `\-', which can be either accessed as `\-' or `\[-]'.

       \[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.

       Entries marked with  `***'  denote  glyphs  for  mathematical  purposes
       (mainly used for DVI output).  Normally, such glyphs have metrics which
       make them unusable in normal text.

       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'
       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 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 glyphs

       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.  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+03C6 the curly glyph.  Unfortunately, most
       font vendors didn't update their fonts to this (incompatible) change in
       Unicode.  At the time of this writing (January 2006), 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.
