       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 `utf8'.

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

       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.

              gives the usual PostScript name of the glyph.

              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 `\(ti'.

       ^      the ISO latin1 `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 latin1 (ISO-8859-1) code
       set, being identical to the Unicode range Latin-1 Supplement.

       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

       \(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
