 .Ss Punctuation and Spacing  
 If punctuation is set apart from words, such as in the phrase  
 .Dq to be \&, or not to be ,  
 it's processed by  
 .Nm  
 according to the following rules:  opening punctuation  
 .Po  
 .Sq \&( ,  
 .Sq \&[ ,  
 and

 If the input is  
 .Xr mdoc 7 ,  
 these rules are also applied to macro arguments when appropriate.  
 .  
 .Pp  
 White-space, in non-literal (normal) mode, is stripped from input and  
 replaced on output by a single space.  Thus, if you wish to preserve multiple  
 spaces, they must be space-escaped or used in a literal display mode, e.g.,  
 .Sq \&Bd \-literal  
 in  
 .Xr mdoc 7 .

   .Sh OUTPUT
   This section documents output details of
   .Nm .
   In general, output conforms to the traditional manual style of a header,
   a body composed of sections and sub-sections, and a footer.
   .Pp
   The text style of output characters (non-macro characters, punctuation,
   and white-space) is dictated by context.
   .Pp
   White-space is generally stripped from input.  This can be changed with
   character escapes (specified in
   .Xr mandoc_char 7 )
   or literal modes (specified in
   .Xr mdoc 7
   and
   .Xr man 7 ) .
   .Pp
   If non-macro punctuation is set apart from words, such as in the phrase
   .Dq to be \&, or not to be ,
   it's processed by
   .Nm ,
   regardless of output format, according to the following rules:  opening
   punctuation
   .Po
   .Sq \&( ,
   .Sq \&[ ,
   and
   .Sq \&{
   .Pc
   is not followed by a space; closing punctuation
   .Po
   .Sq \&. ,
   .Sq \&, ,
   .Sq \&; ,
   .Sq \&: ,
   .Sq \&? ,
   .Sq \&! ,
   .Sq \&) ,
   .Sq \&]
   and
   .Sq \&}
   .Pc
   is not preceded by white-space.
   .
   .Pp
   If the input is
   .Xr mdoc 7 ,
   however, these rules are also applied to macro arguments when appropriate.
   .
   .
   .Ss ASCII Output
   Output produced by
   .Fl T Ns Ar ascii ,
   which is the default, is rendered in standard 7-bit ASCII documented in
   .Xr ascii 7 .
   .Pp
   Font styles are applied by using back-spaced encoding such that an
   underlined character
   .Sq c
   is rendered as
   .Sq _ Ns \e[bs] Ns c ,
   where
   .Sq \e[bs]
   is the back-space character number 8.  Emboldened characters are rendered as
   .Sq c Ns \e[bs] Ns c .
   .Pp
   The special characters documented in
   .Xr mandoc_char 7
   are rendered best-effort in an ASCII equivalent.
   .Pp
   Output width is limited to 78 visible columns unless literal input lines
   exceed this limit.
   .
   .
   .Ss HTML Output
   Output produced by
   .Fl T Ns Ar html
   conforms to HTML-4.01 strict.
   .Pp
   Font styles and page structure are applied using CSS2.  By default, no
   font style is applied to any text, although CSS2 is hard-coded to format
   the basic structure of output.
   .Pp
   The
   .Pa example.style.css
   file documents the range of styles applied to output and, if used, will
   cause rendered documents to appear as they do in
   .Fl T Ns Ar ascii .
   .Pp
   Special characters are rendered in decimal-encoded UTF-8.
   .
   .
   .Ss XHTML Output
   Output produced by
   .Fl T Ns Ar xhtml
   conforms to XHTML-1.0 strict.
   .Pp
   See
   .Sx HTML Output
   for details; beyond generating XHTML tags instead of HTML tags, these
   output modes are identical.
