.Nd mandoc special characters
.\" SECTION
.Sh DESCRIPTION
This documents the special characters and predefined strings accepted by
.Xr mandoc 1
to format
.Xr mdoc 7
and
.Xr man 7
documents. Specific output devices of
.Xr mandoc 1 ,
dictated by the
.Fl T Ns Ar output
argument, will properly render these sequences.
.\" PARAGRAPH
.Pp
Both
.Xr mdoc 7
and
.Xr man 7
encode special characters with
.Sq \eX
.Pq for a one-character escape ,
.Sq \e(XX
.Pq two-character ,
and
.Sq \e[N]
.Pq N-character .
One may generalise
.Sq \e(XX
as
.Sq \e[XX]
and
.Sq \eX
as
.Sq \e[X] .
Predefined strings are functionally similar to special characters, using
.Sq \e*X
.Pq for a one-character escape ,
.Sq \e*(XX
.Pq two-character ,
and
.Sq \e*[N]
.Pq N-character .
One may generalise
.Sq \e*(XX
as
.Sq \e*[XX]
and
.Sq \e*X
as
.Sq \e*[X] .
