+.Sh NAME
+.Nm vis
+.Nd display non-printable characters in a visual format
+.Sh SYNOPSIS
+.Nm
+.Op Fl bcfhlmnostw
+.Op Fl e Ar extra
+.Op Fl F Ar foldwidth
+.Op Ar file ...
+.Sh DESCRIPTION
+.Nm
+is a filter for converting non-printable characters
+into a visual representation.
+It differs from
+.Ql cat -v
+in that
+the form is unique and invertible.
+By default, all non-graphic
+characters except space, tab, and newline are encoded.
+A detailed description of the
+various visual formats is given in
+.Xr vis 3 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl b
+Turns off prepending of backslash before up-arrow control sequences
+and meta characters, and disables the doubling of backslashes.
+This
+produces output which is neither invertible or precise, but does
+represent a minimum of change to the input.
+It is similar to
+.Dq Li cat -v .
+.Pq Dv VIS_NOSLASH
+.It Fl c
+Request a format which displays a small subset of the
+non-printable characters using C-style backslash sequences.
+.Pq Dv VIS_CSTYLE
+.It Fl e Ar extra
+Also encode characters in
+.Ar extra ,
+per
+.Xr svis 3 .
+.It Fl F Ar foldwidth
+Causes
+.Nm
+to fold output lines to foldwidth columns (default 80), like
+.Xr fold 1 ,
+except
+that a hidden newline sequence is used, (which is removed
+when inverting the file back to its original form with
+.Xr unvis 1 ) .
+If the last character in the encoded file does not end in a newline,
+a hidden newline sequence is appended to the output.
+This makes
+the output usable with various editors and other utilities which
+typically don't work with partial lines.
+.It Fl f
+Same as
+.Fl F .
+.It Fl h
+Encode using the URI encoding from RFC 1808.
+.Pq Dv VIS_HTTPSTYLE
+.It Fl l
+Mark newlines with the visible sequence
+.Ql \e$ ,
+followed by the newline.
+.It Fl m
+Encode using the MIME Quoted-Printable encoding from RFC 2045.
+.Pq Dv VIS_MIMESTYLE
+.It Fl n
+Turns off any encoding, except for the fact that backslashes are
+still doubled and hidden newline sequences inserted if
+.Fl f
+or
+.Fl F
+is selected.
+When combined with the
+.Fl f
+flag,
+.Nm
+becomes like
+an invertible version of the
+.Xr fold 1
+utility.
+That is, the output can be unfolded by running the output through
+.Xr unvis 1 .
+.It Fl o
+Request a format which displays non-printable characters as
+an octal number, \eddd.
+.Pq Dv VIS_OCTAL
+.It Fl s
+Only characters considered unsafe to send to a terminal are encoded.
+This flag allows backspace, bell, and carriage return in addition
+to the default space, tab and newline.
+.Pq Dv VIS_SAFE
+.It Fl t
+Tabs are also encoded.
+.Pq Dv VIS_TAB
+.It Fl w
+White space (space-tab-newline) is also encoded.
+.Pq Dv VIS_WHITE
+.El
+.Sh MULTIBYTE CHARACTER SUPPORT
+.Nm
+supports multibyte character input.
+The encoding conversion is influenced by the setting of the
+.Ev LC_CTYPE
+environment variable which defines the set of characters that can be
+copied without encoding.
+.Pp
+When 8-bit data is present in the input,
+.Ev LC_CTYPE
+must be set to the correct locale or to the C locale.
+If the locales of the data and the conversion are mismatched, multibyte
+character recognition may fail and encoding will be performed byte-by-byte
+instead.
+.Sh ENVIRONMENT
+.Bl -tag -width ".Ev LC_CTYPE"
+.It Ev LC_CTYPE
+Specify the locale of the input data.
+Set to C if the input data locale is unknown.
+.Sh SEE ALSO
+.Xr unvis 1 ,
+.Xr svis 3 ,
+.Xr vis 3
+.Sh HISTORY
+The
+.Nm
+command appears in
+.Bx 4.4 .
+Myltibyte character support was added in
+.Nx 6.1
+and
+.Fx 9.2 .
