-.Os
-.Sh NAME
-.Nm preconv
-.Nd recode multibyte UNIX manuals
-.Sh SYNOPSIS
-.Nm preconv
-.Op Fl D Ar enc
-.Op Fl e Ar enc
-.Op Ar file
-.Sh DESCRIPTION
-The
-.Nm
-utility recodes multibyte
-.Ux
-manual files into
-.Xr mandoc 1
-.Po
-or other troff system supporting the
-.Sq \e[uNNNN]
-escape sequence
-.Pc
-input.
-.Pp
-By default, it parses from standard output, determining encoding as
-described in
-.Sx Algorithm .
-.Pp
-Its arguments are as follows:
-.Bl -tag -width Ds
-.It Fl D Ar enc
-The default encoding.
-.It Fl e Ar enc
-The document's encoding.
-.It Ar file
-The input file.
-.El
-.Pp
-The recoded input is written to standard output: Unicode characters in
-the ASCII range are printed as regular ASCII characters, while those
-above this range are printed using the
-.Sq \e[uNNNN]
-format documented in
-.Xr mandoc_char 7 .
-.Pp
-If input bytes are improperly formed in the current encoding, they're
-passed unmodified to standard output.
-For some encodings, such as UTF-8, unrecoverable input sequences will
-cause
-.Nm
-to stop processing and exit.
-.Ss Algorithm
-An encoding is chosen according to the following steps:
-.Bl -enum
-.It
-From the argument passed to
-.Fl e Ar enc .
-.It
-If a BOM exists, UTF\-8 encoding is selected.
-.It
-From the coding tags parsed from
-.Qq File Variables
-on the first two lines of input.
-A file variable is an input line of the form
-.Pp
-.Dl \%.\e\(dq -*- key: val [; key: val ]* -*-
-.Pp
-A coding tag variable is where
-.Cm key
-is
-.Qq coding
-and
-.Cm val
-is the name of the encoding.
-A typical file variable with a coding tag is
-.Pp
-.Dl \%.\e\(dq -*- mode: troff; coding: utf-8 -*-
-.It
-From the argument passed to
-.Fl D Ar enc .
-.It
-If all else fails, Latin\-1 is used.
-.El
-.Pp
-The
-.Nm
-utility recognises the UTF\-8, us\-ascii, and latin\-1 encodings as
-passed to the
-.Fl e
-and
-.Fl D
-arguments, or as coding tags.
-Encodings are matched case-insensitively.

-.Sh STANDARDS
-The

-utility references the US-ASCII character set standard, ANSI_X3.4\-1968;
-the Latin\-1 character set standard, ISO/IEC 8859\-1:1998; the UTF\-8
-character set standard; and UCS (Unicode), ISO/IEC 10646.
-.Sh HISTORY
-The
-.Nm
-utility first appeared in the GNU troff
-.Pq Dq groff
-system in December 2005, authored by Tomohiro Kubota and Werner
-Lemberg.
-The implementation that is part of the
-.Xr mandoc 1
-utility appeared in May 2011.
