+.Ss UTF-8 Output
+Use
+.Fl T Ns Cm utf8
+to force a UTF-8 locale.
+See
+.Sx Locale Output
+for details and options.
+.Ss Locale Output
+Locale-depending output encoding is triggered with
+.Fl T Ns Cm locale .
+This option is not available on all systems: systems without locale
+support, or those whose internal representation is not natively UCS-4,
+will fall back to
+.Fl T Ns Cm ascii .
+See
+.Sx ASCII Output
+for font style specification and available command-line arguments.
+.Ss ASCII Output
+Output produced by
+.Fl T Ns Cm 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.
+If no equivalent is found,
+.Sq \&?
+is used instead.
+.Pp
+Output width is limited to 78 visible columns unless literal input lines
+exceed this limit.
+.Pp

+.It Cm width Ns = Ns Ar width
+The output width is set to

+.Ss HTML Output
+Output produced by
+.Fl T Ns Cm html
+conforms to HTML-4.01 strict.
+.Pp
+The
+.Pa example.style.css
+file documents style-sheet classes available for customising output.
+If a style-sheet is not specified with
+.Fl O Ns Ar style ,
+.Fl T Ns Cm html
+defaults to simple output readable in any graphical or text-based web
+browser.
+.Pp
+Special characters are rendered in decimal-encoded UTF-8.

+.Bl -tag -width Ds
+.It Cm includes Ns = Ns Ar fmt
+The string
+.Ar fmt ,
+for example,
+.Ar ../src/%I.html ,
+is used as a template for linked header files (usually via the
+.Sq \&In
+macro).
+Instances of
+.Sq \&%I
+are replaced with the include filename.
+The default is not to present a
+hyperlink.
+.It Cm man Ns = Ns Ar fmt
+The string
+.Ar fmt ,
+for example,
+.Ar ../html%S/%N.%S.html ,
+is used as a template for linked manuals (usually via the
+.Sq \&Xr
+macro).
+Instances of
+.Sq \&%N
+and
+.Sq %S
+are replaced with the linked manual's name and section, respectively.
+If no section is included, section 1 is assumed.
+The default is not to
+present a hyperlink.
+.It Cm style Ns = Ns Ar style.css
+The file
+.Ar style.css
+is used for an external style-sheet.
+This must be a valid absolute or

+.Qq Adobe-3.0
+Level-2 pages may be generated by

+Output pages default to letter sized and are rendered in the Times font

+Margins are calculated as 1/9 the page length and width.
+Line-height is 1.4m.

+.Ar legal ,
+or
+.Ar letter .
+You may also manually specify dimensions as
+.Ar NNxNN ,
+width by height in millimetres.
