.\" --------------------------------------------------------------------
.
This manual page lists the standard
.B groff
input characters.
.
The output characters in this document will look different depending
on which output device was chosen (with option
.B \-T
for the
.BR man (1)
program or the roff formatter).
.
Only the characters that are available for the device that
is being used to print or view this manual page will be
.ie \n(.g displayed (the device currently used is `\*(.T').
.el displayed.
.
.
.P
In the actual version, 
.B groff
provides only 8-bit characters for direct input and named characters
for further glyphs.
.
On ASCII platforms, 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 Latin-1
.RI ( ISO-8859-1 )
code set.
.
On EBCDIC platforms, only the code page
.B cp1047
is supported (which contains the same characters as Latin-1).
.
It is rather straightforward (for the experienced user) to set up other
8bit encodings like
.IR Latin-2 ;
since
.B groff
will use Unicode in the next major version, no additional encodings
are provided.
.
.
.P
All roff systems provide the concept of named characters.
.
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 characters are used for all
characters outside of the 7-bit ASCII range.
.
.
.P
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
.BR \e\e ,
.BR \e' ,
.BR \e` ,
.BR \e- ,
.BR \e. ,
and
.BR \ee ;
see
.BR groff (@MAN7EXT@).
.
.
.P
In groff, all of these different types of characters can be tested
positively with the
.B .if\ c
conditional.
.
.
.\" --------------------------------------------------------------------
.SH REFERENCE
.\" --------------------------------------------------------------------
.
In this section, the characters in groff are specified in tabular
form.
.
The meaning of the columns is as follows.
.
.
.TP
.I "Output"
shows how the character 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 name"
specifies how the character is input either directly by a key on the
keyboard, or by a groff escape sequence.
.
.
.TP
.I "Input code"
applies to characters 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).
.
.
.TP
.I "PostScript name"
gives the usual PostScript name of the output character.
.
.
.\" --------------------------------------------------------------------
.SS "ASCII Characters"
.\" --------------------------------------------------------------------
.
These are the basic characters having 7-bit ASCII code values.
.
These are identical to the first 127 characters of the character
standards ISO-8859-1 (Latin-1) and Unicode (range
.IR "C0 Controls and Basic Latin" ).
.
To save space, not every code has an entry in the following because
the following code ranges are well known.
.
.TP
0\-32
Control characters (print as themselves).
.
.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\-z (print as themselves).
.
.TP
127
Control character (prints as itself).
.
.P
The remaining ranges constitute the printable, non-alphanumeric ASCII
characters; only these are listed below.
.
As can be seen in the table below, most of these characters print as
themselves; the only exceptions are the following characters:
.
.TP
.B \`
the ISO Latin-1 `Grave Accent' (code\ 96) prints as `, a left single
quotation mark,
.
.TP
.B \*(aq
the ISO Latin-1 `Apostrophe' (code\ 39) prints as ', a right single
quotation mark; the corresponding ISO Latin-1 characters can be obtained
with
.B \e`
and
.BR \e(aq .
.
.TP
.B -
the ISO Latin-1 `Hyphen, Minus Sign' (code\ 45) prints as a hyphen; a
minus sign can be obtained with
.BR \e- .
.
.TP
.B ~
the ISO Latin-1 `Tilde' (code\ 126); a larger glyph can be obtained
with
.BR \e(ti .
.
.TP
.B ^
the ISO Latin-1 `Circumflex Accent' (code\ 94); a larger glyph can be
obtained with
.BR \e(ha .

.
These characters have character codes between 128 and\ 255.
.
They are interpreted as characters according to the
.I Latin-1
.RI ( iso-8859-1 )
code set, being identical to the Unicode range
.IR "C1 Controls and Latin-1 Supplement" .
.
.TP
128\-159
.
the C1 Controls; they print as themselves, but the effect is mostly
undefined.
.
.TP
160
.
the ISO Latin-1
.I no-break space
is mapped to
.BR `\e\ ' ,
the escaped space character.
.
.TP
173
.
the soft hyphen control character (prints as itself).
.
groff never use this character for output (thus it is omitted in the table
below); the input character\ 173 is mapped onto
.BR \e% .
.
.
.P
The remaining ranges (161\-172, 174\-255), called the
.I Latin-1 Supplement
in Unicode, 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 named character
equivalent; see next section.

.SS "Named Characters"
.\" --------------------------------------------------------------------
.
The named character idiom is the standard way to specify special
characters in roff systems.
.
They can be embedded into the document text by using escape sequences.
.
.BR groff (@MAN7EXT@)
describes how these escape sequences look.
.
The character names can consist of quite arbitrary characters from the
ASCII or Latin-1 code set, not only alphanumeric characters.
.
Here some examples:
.
.TP
.BI \e c
named character having the name
.IR c ,
which consists of a single character (length\ 1).
.
.TP
.BI \e( ch
named character having the 2-character name
.IR ch .
.
.TP
.BI \e[ char_name ]
named character having the name
.I char_name
(having length 1, 2, 3, .\|.\|.).
.
.
.P
In groff, each 8bit input character can also referred to by the construct
.BI \en[char n ]
where
.I n
is the decimal code of the character, a number between 0 and\ 255
without leading zeros.
.
They are mapped onto glyph entities using the
.B .trin
request.
.
Moreover, new character names can be created by the
.B .char
request; see
.BR groff (@MAN7EXT@).
