NAME

4     mandoc_char — mandoc special characters

DESCRIPTION

7     This page documents the roff(7) escape sequences accepted by mandoc(1) to
8     represent special characters in mdoc(7) and man(7) documents.
9
10     The rendering depends on the mandoc(1) output mode; it can be inspected
11     by calling man(1) on the mandoc_char manual page with different -T argu‐
12     ments.  In ASCII output, the rendering of some characters may be hard to
13     interpret for the reader.  Many are rendered as descriptive strings like
14     "<integral>", "<degree>", or "<Gamma>", which may look ugly, and many are
15     replaced by similar ASCII characters.  In particular, accented characters
16     are usually shown without the accent.  For that reason, try to avoid
17     using any of the special characters documented here except those dis‐
18     cussed in the DESCRIPTION, unless they are essential for explaining the
19     subject matter at hand, for example when documenting complicated mathe‐
20     matical functions.
21
22     In particular, in English manual pages, do not use special-character
23     escape sequences to represent national language characters in author
24     names; instead, provide ASCII transcriptions of the names.
25
26   Dashes and Hyphens
27     In typography there are different types of dashes of various width: the
28     hyphen (‐), the en-dash (–), the em-dash (—), and the mathematical minus
29     sign (−).
30
31     Hyphens are used for adjectives; to separate the two parts of a compound
32     word; or to separate a word across two successive lines of text.  The
33     hyphen does not need to be escaped:
34
35           blue-eyed
36           lorry-driver
37
38     The en-dash is used to separate the two elements of a range, or can be
39     used the same way as an em-dash.  It should be written as ‘\(en’:
40
41           pp. 95\(en97.
42           Go away \(en or else!
43
44     The em-dash can be used to show an interruption or can be used the same
45     way as colons, semi-colons, or parentheses.  It should be written as
46     ‘\(em’:
47
48           Three things \(em apples, oranges, and bananas.
49           This is not that \(em rather, this is that.
50
51     In roff(7) documents, the minus sign is normally written as ‘\-’.  In
52     manual pages, some style guides recommend to also use ‘\-’ if an ASCII
53     0x2d “hyphen-minus” output glyph that can be copied and pasted is desired
54     in output modes supporting it, for example in -T utf8 and -T html.  But
55     currently, no practically relevant manual page formatter actually
56     requires that subtlety, so in manual pages just write plain ‘-’ to repre‐
57     sent hyphen, minus, and hyphen-minus.
58
59     If a word on a text input line contains a hyphen, a formatter may decide
60     to insert an output line break after the hyphen if that helps filling the
61     current output line, but the whole word would overflow the line.  If it
62     is important that the word is not broken across lines in this way, a
63     zero-width space (‘\&’) can be inserted before or after the hyphen.
64     While mandoc(1) never breaks the output line after hyphens adjacent to a
65     zero-width space, after any of the other dash- or hyphen-like characters
66     represented by escape sequences, or after hyphens inside words in macro
67     arguments, other software may not respect these rules and may break the
68     line even in such cases.
69
70     Some roff(7) implementations contains dictionaries allowing to break the
71     line at syllable boundaries even inside words that contain no hyphens.
72     Such automatic hyphenation is not supported by mandoc(1), which only
73     breaks the line at whitespace, and inside words only after existing
74     hyphens.
75
76   Spaces
77     To separate words in normal text, for indenting and alignment in literal
78     context, and when none of the following special cases apply, just use the
79     normal space character (‘ ’).
80
81     When filling text, output lines may be broken between words, i.e. at
82     space characters.  To prevent a line break between two particular words,
83     use the unpaddable non-breaking space escape sequence (‘\ ’) instead of
84     the normal space character.  For example, the input string “number\ 1”
85     will be kept together as “number 1” on the same output line.
86
87     On request and macro lines, the normal space character serves as an argu‐
88     ment delimiter.  To include whitespace into arguments, quoting is usually
89     the best choice; see the MACRO SYNTAX section in roff(7).  In some cases,
90     using the non-breaking space escape sequence (‘\ ’) may be preferable.
91
92     To escape macro names and to protect whitespace at the end of input
93     lines, the zero-width space (‘\&’) is often useful.  For example, in
94     mdoc(7), a normal space character can be displayed in single quotes in
95     either of the following ways:
96
97           .Sq " "
98           .Sq \ \&
99
100   Quotes
101     On request and macro lines, the double-quote character (‘"’) is handled
102     specially to allow quoting.  One way to prevent this special handling is
103     by using the ‘\(dq’ escape sequence.
104
105     Note that on text lines, literal double-quote characters can be used ver‐
106     batim.  All other quote-like characters can be used verbatim as well,
107     even on request and macro lines.
108
109   Accents
110     In output modes supporting such special output characters, for example -T
111     pdf, and sometimes less consistently in -T utf8, some roff(7) formatters
112     convert the following ASCII input characters to the following Unicode
113     special output characters:
114
115           `       U+2018    left single quotation mark
116           '       U+2019    right single quotation mark
117           ~       U+02DC    small tilde
118           ^       U+02C6    modifier letter circumflex
119
120     In prose, this automatic substitution is often desirable; but when these
121     characters have to be displayed as plain ASCII characters, for example in
122     source code samples, they require escaping to render as follows:
123
124           \(ga    U+0060    grave accent
125           \(aq    U+0027    apostrophe
126           \(ti    U+007E    tilde
127           \(ha    U+005E    circumflex accent
128
129   Periods
130     The period (‘.’) is handled specially at the beginning of an input line,
131     where it introduces a roff(7) request or a macro, and when appearing
132     alone as a macro argument in mdoc(7).  In such situations, prepend a
133     zero-width space (‘\&.’) to make it behave like normal text.
134
135     Do not use the ‘\.’ escape sequence.  It does not prevent special han‐
136     dling of the period.
137
138   Backslashes
139     To include a literal backslash (‘\’) into the output, use the (‘\e’)
140     escape sequence.
141
142     Note that doubling it (‘\\’) is not the right way to output a backslash.
143     Because mandoc(1) does not implement full roff(7) functionality, it may
144     work with mandoc(1), but it may have weird effects on complete roff(7)
145     implementations.

SPECIAL CHARACTERS

148     Special characters are encoded as ‘\X’ (for a one-character escape),
149     ‘\(XX’ (two-character), and ‘\[N]’ (N-character).  For details, see the
150     Special Characters subsection of the roff(7) manual.

PREDEFINED STRINGS

551     Predefined strings are inherited from the macro packages of historical
552     troff implementations.  They are not recommended for use, as they differ
553     across implementations.  Manuals using these predefined strings are
554     almost certainly not portable.
555
556     Their syntax is similar to special characters, using ‘\*X’ (for a
557     one-character escape), ‘\*(XX’ (two-character), and ‘\*[N]’
558     (N-character).  For details, see the Predefined Strings subsection of the
559     roff(7) manual.

UNICODE CHARACTERS

592     The escape sequences
593
594           \[uXXXX] and \C'uXXXX'
595
596     are interpreted as Unicode codepoints.  The codepoint must be in the
597     range above U+0080 and less than U+10FFFF.  For compatibility, the hexa‐
598     decimal digits ‘A’ to ‘F’ must be given as uppercase characters, and
599     points must be zero-padded to four characters; if greater than four char‐
600     acters, no zero padding is allowed.  Unicode surrogates are not allowed.
601

NUMBERED CHARACTERS

603     For backward compatibility with existing manuals, mandoc(1) also supports
604     the
605
606           \N'number' and \[charnumber]
607
608     escape sequences, inserting the character number from the current charac‐
609     ter set into the output.  Of course, this is inherently non-portable and
610     is already marked as deprecated in the Heirloom roff manual; on top of
611     that, the second form is a GNU extension.  For example, do not use \N'34'
612     or \[char34], use \(dq, or even the plain ‘"’ character where possible.
613

COMPATIBILITY

615     This section documents compatibility between mandoc and other troff
616     implementations, at this time limited to GNU troff ("groff").
617
618     -   The \N'' escape sequence is limited to printable characters; in
619         groff, it accepts arbitrary character numbers.
620     -   In -Tascii, the \(ss, \(nm, \(nb, \(nc, \(ib, \(ip, \(pp, \[sum],
621         \[product], \[coproduct], \(gr, \(-h, and \(a. special characters
622         render differently between mandoc and groff.
623     -   In -Thtml, the \(~=, \(nb, and \(nc special characters render differ‐
624         ently between mandoc and groff.
625     -   The -Tps and -Tpdf modes format like -Tascii instead of rendering
626         glyphs as in groff.
627     -   The \[radicalex], \[sqrtex], and \(ru special characters have been
628         omitted from mandoc either because they are poorly documented or they
629         have no known representation.

CAVEATS

639     The predefined string ‘\*(Ba’ mimics the behaviour of the ‘|’ character
640     in mdoc(7); thus, if you wish to render a vertical bar with no side
641     effects, use the ‘\(ba’ escape.
