.SH DESCRIPTION
.\" ====================================================================
.
This manual page lists the standard
.B 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
.B \-T
for the
.BR 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
.ie \n(.g \[oq](N/A)\[cq]; the device currently used is \[oq]\*(.T\[cq].
.el \[oq](N/A)\[cq].
.
.
.P
In the actual version,
.B 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
.I \%latin1
.RI ( \%ISO-8859-1 )
code set by default.
.
This mapping is contained in the file \f(CWlatin1.tmac\fP
and can be changed by loading a different input encoding.
.
Note that some of the input characters are reserved by
.BR groff ,
either for internal use or for special input purposes.
.
On EBCDIC platforms, only code page
.I cp1047
is supported (which contains the same characters as \%latin1; the
input encoding file is called \f(CWcp1047.tmac\fP).
.
Again, some input characters are reserved for internal and special
purposes.
.
.
.P
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.
.
.
.P
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
\[oq]\f(CW\e\e\fP\[cq],
\[oq]\f(CW\e\[aq]\fP\[cq],
\[oq]\f(CW\e\[ga]\fP\[cq],
\[oq]\f(CW\e\-\fP\[cq],
\[oq]\f(CW\e.\fP\[cq],
and
\[oq]\f(CW\ee\fP\[cq];
see
.BR groff (7).
.
.
.P
In groff, all of these different types of characters and glyphs can be
tested positively with the \[oq]\f(CW.if\ c\fP\[cq] conditional.
.
.
.\" ====================================================================
.SH REFERENCE
.\" ====================================================================
.
In this section, the glyphs in groff are specified in tabular
form.
.
The meaning of the columns is as follows.
.
.
.TP
.I "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.
.
.
.TP
.I "Input"
specifies how the glyph is input either directly by a key on the
keyboard, or by a groff escape sequence.
.
.
.TP
.I "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.
.
.
.TP
.I "PostScript"
gives the usual PostScript name of the glyph.
.
.
.TP
.I "Unicode"
is the glyph name used in composite glyph names.
.
The names in the Unicode column look like
.B u0021
or
.BR u0041_0300 .
.
In groff, the corresponding Unicode characters can be constructed
by adding a backslash and a pair of square brackets, for example
.B \e[u0021]
or
.BR \e[u0041_0300] .
.
.
.\" ====================================================================
.SS "7-bit Character Codes 32\(en126"
.\" ====================================================================
.
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
.IR "Basic Latin" ).
.
The glyph names used in composite glyph names are \[oq]u0020\[cq] up
to \[oq]u007E\[cq].
.
.
.P
Note that input characters in the range \%0\-31 and character 127 are
.I not
printable characters.
.
Most of them are invalid input characters for
.B groff
anyway, and the valid ones have special meaning.
.
For EBCDIC, the printable characters are in the range \%66\-255.
.
.
.TP
48\-57
Decimal digits 0 to\ 9 (print as themselves).
.
.
.TP
65\-90
Upper case letters A\-Z (print as themselves).
.
.
.TP
97\-122
Lower case letters a\(enz (print as themselves).
.
.
.P
Most of the remaining characters not in the just described ranges print
as themselves; the only exceptions are the following characters:
.
.
.TP
.B \`
the ISO \%latin1 \[oq]Grave Accent\[cq] (code\ 96) prints as \[oq], a
left single quotation mark (Unicode u2018).
The same output glyph can be requested explicitly
with \[oq]\f(CW\e(oq\fP\[cq].
The original character can be obtained
with \[oq]\f(CW\e`\fP\[cq] (Unicode u0060).
.
.
.TP
.B \*(aq
the ISO \%latin1 \[oq]Apostrophe\[cq] (code\ 39) prints as \[cq],
a right single quotation mark (Unicode u2019).
The same output glyph is commonly used in typography to represent
a punctation apostrophe, for example in contractions.
It can be requested explicitly with \[oq]\f(CW\e(cq\fP\[cq].
The original character can be obtained with
\[oq]\f(CW\e(aq\fP\[cq] (Unicode u0027).
.
.
.TP
.B -
the ISO \%latin1 \[oq]Hyphen, Minus Sign\[cq] (code\ 45) prints as a
hyphen (Unicode u2010).
The same output glyph can be requested explicitly
with \[oq]\f(CW\e(hy\fP\[cq].
A minus sign can be obtained with \[oq]\f(CW\e-\fP\[cq] (Unicode u2212).
.
.
.TP
.B ~
the ISO \%latin1 \[oq]Tilde\[cq] (code\ 126) is reduced in size to be
usable as a diacritic (Unicode u02DC).
A larger glyph can be obtained with
\[oq]\f(CW\e(ti\fP\[cq] (Unicode u007E).
.
.
.TP
.B ^
the ISO \%latin1 \[oq]Circumflex Accent\[cq] (code\ 94) is reduced in
size to be usable as a diacritic (Unicode u02C6); a larger glyph
can be obtained with \[oq]\f(CW\e(ha\fP\[cq] (Unicode u005E).

.SS "Named Glyphs"
.\" ====================================================================
.
Glyph names can be embedded into the document text by using escape
sequences.
.
.BR 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:
.
.TP
\f(CW\e(\fP\fIch\fP
A glyph having the 2-character name
.IR ch .
.
.TP
\f(CW\e[\fP\,\fIchar_name\/\fP\f(CW]\fP
A glyph having the name
.I char_name
(having length 1, 2, 3, \&.\|.\|.).
.
Note that \[oq]\fIc\fP\[cq] is not the same as
\[oq]\f(CW\e[\fP\,\fIc\/\fP\f(CW]\fP\[cq] (\,\fIc\fP\ a single
character): The latter is internally mapped to glyph name
\[oq]\e\fIc\fP\[cq].
.
By default, groff defines a single glyph name starting with a
backslash, namely \%\[oq]\e-\[cq], which can be either accessed as
\[oq]\f(CW\e\-\fP\[cq] or \[oq]\f(CW\e[-]\fP\[cq].
.
.TP
\f(CW\e[\fP\,\fIbase_glyph composite_1 composite_2 \&.\|.\|.\/\fP\
\f(CW]\fP
A composite glyph; see below for a more detailed description.
.
.
.P
In groff, each \%8-bit input character can also referred to by the
construct
\[oq]\f(CW\e[char\fP\,\fIn\/\fP\f(CW]\fP\[cq] where
.I n
is the decimal code of the character, a number between 0 and\ 255
without leading zeros (those entities are
.I not
glyph names).
.
They are normally mapped onto glyphs using the \f(CW.trin\fP request.
.
.
.P
Another special convention is the handling of glyphs with names directly
derived from a Unicode code point; this is shown in the
\[oq]Unicode\[cq] column of the table below.
.
In general, all glyphs not having a name as listed in this manual page
can be accessed with the
\[oq]\f(CW\e[u\fP\,\fIXXXX\/\fP\f(CW]\fP\[cq]
construct.
.
Refer to section \[lq]Using Symbols\[rq] in
.IR "Groff: The GNU Implementation of troff" ,
the
.I groff
Texinfo manual,
which describes how
.I groff
glyph names are constructed.
.
.
.P
Moreover, new glyph names can be created by the \f(CW.char\fP request;
see
.BR groff (7).
.
.P
In the following, a plus sign \[oq]+\[cq] in the \[oq]Notes\[cq] column
indicates that this particular glyph name appears in the PS version of
the original troff documentation, CSTR\ 54.
.
.P
Entries marked with \[oq]***\[cq] denote glyphs for mathematical
purposes (mainly used for DVI output).
.
Normally, such glyphs have metrics which make them unusable in normal
text.

.I Brackets
.P
The extensible bracket pieces are font-invariant glyphs.
.
In classical troff only one glyph was available to vertically extend
brackets, braces, and parentheses: \[oq]bv\[cq].
.
We map it rather arbitrarily to u23AA.
.
.P
Note that not all devices contain extensible bracket pieces which can
be piled up with \[oq]\f(CW\eb\fP\[cq] due to the restrictions of the
escape's piling algorithm.
.
A general solution to build brackets out of pieces is the following
macro:
.
.P
.nf
.RS
.ft C
\&.\e" Make a pile centered vertically 0.5em
\&.\e" above the baseline.
\&.\e" The first argument is placed at the top.
\&.\e" The pile is returned in string 'pile'
\&.eo
\&.de pile-make
\&.  nr pile-wd 0
\&.  nr pile-ht 0
\&.  ds pile-args
\&.
\&.  nr pile-# \en[.$]
\&.  while \en[pile-#] \e{\e
\&.    nr pile-wd (\en[pile-wd] >? \ew'\e$[\en[pile-#]]')
\&.    nr pile-ht +(\en[rst] - \en[rsb])
\&.    as pile-args \ev'\en[rsb]u'\e"
\&.    as pile-args \eZ'\e$[\en[pile-#]]'\e"
\&.    as pile-args \ev'-\en[rst]u'\e"
\&.    nr pile-# -1
\&.  \e}
\&.
\&.  ds pile \ev'(-0.5m + (\en[pile-ht]u / 2u))'\e"
\&.  as pile \e*[pile-args]\e"
\&.  as pile \ev'((\en[pile-ht]u / 2u) + 0.5m)'\e"
\&.  as pile \eh'\en[pile-wd]u'\e"
\&..
\&.ec
.ft
.RE
.fi
.
.P
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 \[oq]lf\[cq] and \[oq]rf\[cq] which provide
the \[oq]floor\[cq] operator.
.
Other devices (most notably for DVI output) don't unify such
glyphs.
.
For this reason, the four glyphs \[oq]lf\[cq], \[oq]rf\[cq],
\[oq]lc\[cq], and \[oq]rc\[cq] are not unified with similarly looking
bracket pieces.
.
In
.BR groff ,
only glyphs with long names are guaranteed to pile up correctly for all
devices (provided those glyphs exist).

.P
.I Greek glyphs
.P
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 \[oq]phi\[cq] and \[oq]phi1\[cq] also
change its meaning if used for mathematics, thus compatibility
problems are likely to happen \[en] being conservative, groff
currently assumes that \[oq]phi\[cq] in a PostScript symbol font is
the stroked version.
.P
In groff, symbol \[oq]\f(CW\e[*f]\fP\[cq] always denotes the stroked
version of phi, and \[oq]\f(CW\e[+f]\fP\[cq] the curly variant.
